Underground Shopping Malls in Seoul: A Complete Guide for Foreigners (2026)

One of the odder moments a first-time visitor has in Seoul happens on the subway. You get off at your stop expecting stairs to the street. Instead, you walk into racks of clothing, cosmetics counters, phone case stalls, and a hallway that seems to keep going.

You check the map again. Yes, this is still the subway station.

Seoul's underground shopping culture is bigger than most visitors expect, and a lot of it connects directly to the subway system. You can spend an entire afternoon shopping without ever going outside, which matters more than it sounds like it should once you've dealt with a Seoul summer or a January cold snap.

Here's the part that trips people up, though. Not every underground shopping area works the same way. Some are individually owned stalls that have been there for decades. Others are run by a single company with a directory and card readers at every register. Knowing the difference before you go saves you a fair amount of confusion once you're actually down there.

Before diving in, it helps to already have a working map app open. Our Naver Map Guide for Foreigners in Korea covers why the app you're used to back home won't get you through a Seoul subway station the same way.

Why "Underground Shopping Mall" Doesn't Mean One Thing in Seoul

In Seoul, the subway isn't just transportation. It's woven into the city's indoor infrastructure. Big stations connect to shopping arcades, department stores, office towers, and bus terminals, so what starts as a line transfer can turn into an hour of browsing before you ever reach daylight.

But here's what most guides skip: these underground shopping areas didn't all grow the same way, and that difference shapes your whole experience.

Some, like Goto Mall or the Gangnam Station underground shopping center, are decades-old arcades built when the subway lines went in. They're run by merchant associations, meaning each stall is basically its own small business. Others, like COEX, are single corporate complexes with one owner, one directory, and one set of store policies across the board.

That's the root of nearly every confusing moment foreigners run into down there: why some stalls only take cash, why receipts aren't guaranteed, why there's no help desk to complain to, and why the layout feels more like a market than a mall. It's not random. It's just two different business models sharing the word "underground."

Why This Matters for Your Trip

If you expect the same experience everywhere, a few things can catch you off guard. A card reader that isn't there. A "no exchange" sign only in Korean. A hallway that looks exactly like the one you just walked through five minutes ago.

None of that makes underground shopping a bad plan. It's actually one of the more efficient ways to shop in Seoul: weatherproof, subway-connected, and often noticeably cheaper than the department stores sitting right above it. You just want to walk in knowing which kind of underground mall you're in before your card gets declined at a cash-only stall.

Because many underground shopping areas are connected directly to subway stations, our Seoul Subway Guide for Foreigners is useful if you are still getting comfortable with Seoul's subway system.

1. Goto Mall: The Best Starting Point for First-Time Visitors

If someone asked which underground shopping area to try first, Goto Mall would be near the top of the list.

It sits beneath Express Bus Terminal Station, where subway Lines 3, 7, and 9 all meet. The official Seoul tourism guide lists it as the largest underground shopping center in Gangnam, with roughly 620 stores stretched across two corridors totaling about 880 meters. It's open daily from 10:00 a.m. to 10:00 p.m., year-round, except for closures around Seollal and Chuseok.

What's actually on the shelves:

Clothing
Accessories
Cosmetics
Interior and home goods
Handmade items
Flowers

The atmosphere isn't polished the way a Western mall is. It's closer to a massive collection of small independent shops lined up along a corridor, and that's exactly what makes it interesting if you want to see how everyday Korean retail shopping actually works, not the version built for tourists.

How to Get There

Take Line 3, 7, or 9 to Express Bus Terminal Station. The official listing points visitors toward Exit 8-1 for direct access to Goto Mall.

Don't assume the first exit you see is the one you want. Express Bus Terminal is a large transportation hub connected to bus terminals, department stores, and duty-free shopping, so give yourself a few extra minutes to follow the signs.

2. Gangnam Station Underground Shopping Center

Above ground, Gangnam means skyscrapers, cafés, and beauty clinics. Below ground, the mood shifts.

This underground shopping center runs beneath Gangnam Station, spanning the connection between Line 2 and the Sinbundang Line. The official Seoul tourism guide describes it as popular with young office workers and college students, filled with affordable fashion and beauty stores. Current listed hours run 9:00 a.m. to 10:00 p.m. daily, with access near Exit 8.

Who Should Visit?

Travelers interested in Korean street fashion
Visitors after affordable accessories
Beauty shoppers comparing prices
Anyone already spending the day in Gangnam

It's also a solid backup plan the moment the weather turns. You can move straight from the subway into shopping without committing to a long walk outdoors.

3. Myeongdong Underground Shopping Center

Myeongdong is already one of Seoul's busiest shopping streets, so heading underground there might sound unnecessary. It isn't.

The Myeongdong Underground Shopping Center connects Myeongdong and City Hall through a covered passage, with Euljiro 1-ga Station (Line 2) as the closest stop.

According to the official Seoul tourism guide, the shopping center itself runs from 9:00 a.m. to 10:00 p.m., while the underground passage stays open 24 hours. It connects directly to Lotte Young Plaza, Lotte Department Store Avenuel, Noon Square, the Ibis Ambassador Hotel, and the Sogong Underground Shopping Center.

What you'll find here:

Cosmetics
Clothing
Accessories
Nail and beauty services
Small everyday goods

That distinction between the passage and the shops matters. A 24-hour underground passage doesn't mean every store inside is open 24 hours. It's one of the easiest mix-ups for visitors to make, especially late at night.

4. Sogong Underground Shopping Center

Sogong has a different feel than the younger, trend-driven energy around Gangnam or Myeongdong's main strip.

This underground center connects the City Hall area with Myeongdong and has a longer history as a downtown shopping destination, dating back to when it was one of the most popular shopping spots in the city during the 1980s. The official Seoul tourism guide notes it for regional products, pottery, and traditional Korean handicrafts, and it connects directly to Lotte Department Store, Lotte Young Plaza, and Avenuel.

One note here: exact current operating hours vary across sources, with some listings showing hours closer to 8:00 a.m. to 10:00 p.m. on weekdays. Since it isn't consistently confirmed across official channels, check the posted hours at the entrance rather than planning your day around a specific closing time.

This is a good stop if you want to pair modern shopping with more traditional Korean products in one visit.

5. Jonggak Underground Shopping Center

If Jongno and Insadong are already on your itinerary, Jonggak Underground Shopping Center is an easy add-on.

It sits in one of central Seoul's busiest areas, with a strong fashion focus that leans toward a younger crowd. The official Seoul tourism guide notes that Insadong, the city's most famous traditional street, is only a 5 to 10 minute walk away.

That makes for a natural pairing: modern retail underground, then a walk into traditional streets, teahouses, and galleries, all without burning half a day getting between neighborhoods. It's also smaller and quieter than Goto Mall, so it's a calmer place to browse if crowds aren't your thing.

6. COEX Mall: A Completely Different Model

COEX belongs in this list because it shows the other side of Seoul's underground retail scene entirely.

This isn't a small-shop arcade. COEX is a large, modern underground complex in Samseong, run by a single operator. The official Seoul tourism guide describes it as one of Asia's largest underground shopping malls, home to clothing and accessory stores, restaurants, cafés, a cinema, and attractions like the COEX Aquarium and the Starfield Library.

Think of the contrast this way:

Goto Mall = independent stalls, bargain-style shopping, cash preferred.
COEX = single company, card payment everywhere, formal tax refund process.

If you want to understand Seoul's traditional underground shopping culture, Goto Mall shows it best. If you want a polished, air-conditioned shopping day with dining and entertainment built in, COEX is the easier choice.

How Payment and Refunds Actually Work Down There

This is where the ownership difference shows up in your wallet.

At COEX, cards work at nearly every register, and most participating stores can process an immediate tax refund at checkout once your purchase clears the minimum threshold.

At Goto Mall, Gangnam Station, Myeongdong, Sogong, or Jonggak, don't assume the same. Plenty of individual stalls prefer cash, especially at discount prices, and some don't issue a printed receipt for a cash sale. No receipt generally means no return and no exchange, even for something as simple as the wrong size. A number of stalls also post their own no-refund policy, which Korean consumer protection rules generally allow as long as it was stated before you paid.

Not every underground store participates in Korea's tax refund system just because it sells to tourists. If a refund matters to your purchase, ask before you pay, and look for the store's own tax-refund signage rather than assuming. Planning to spend more on cosmetics or fashion? Learn how tax refunds work in Korea before making a larger purchase.

What Can Foreigners Actually Buy Underground?

It depends heavily on which mall you're in, but a few categories show up almost everywhere.

Clothing

Small underground stores tend to carry inexpensive Korean-style clothing, seasonal basics, and casual pieces. Don't expect extensive English signage or a proper fitting room at every stall.

Accessories

Hair accessories, jewelry, bags, socks, and hats are everywhere, and they're a lot easier to pack home than bulkier souvenirs.

Beauty Products

Beauty stores cluster heavily around Gangnam and Myeongdong. If Korean skincare is the main goal, compare prices against a major retailer rather than assuming the underground stall is automatically cheaper. Sometimes it is. Sometimes it isn't.

Home and Traditional Goods

Goto Mall is strong for interior items, flowers, and handmade goods, while Sogong leans into pottery and regional crafts you won't find as easily elsewhere.

Are Underground Shopping Malls Actually Cheaper?

Sometimes. Don't treat "underground" as a synonym for "cheap," though.

Some stores are small independent retailers running on thin margins. Others sit inside a major commercial complex with pricing to match. It varies by product, brand, and season.

A simple habit helps here: if something catches your eye, take a photo, check two or three nearby stalls selling something similar, then decide. That small pause has saved plenty of shoppers from buying the first thing they saw, only to find a better price five minutes later.

Step-by-Step: How to Navigate Without Getting Lost

Step 1: Remember the station and exit number, not just the direction you came from

"Express Bus Terminal Station, Exit 8-1, Goto Mall" is a far better reference point than "I came in from over there."

Step 2: Take a photo of the exit sign before you start browsing

It sounds almost too basic to mention. Do it anyway. When you're ready to leave, that photo saves you from wandering through several connected corridors trying to remember which one led back outside.

Step 3: Open your map app before you go underground, not after you're lost

Our Naver Map Guide for Foreigners in Korea covers how to search Korean locations effectively, which matters more once you lose GPS signal underground.

Step 4: Don't assume every exit leads to the street

Some lead into department stores. Some lead to another subway line entirely. That's normal in Seoul's connected stations, not a sign you're going the wrong way.

Step 5: Carry a mix of cash and card

Card for COEX and larger stores, cash for the smaller merchant stalls where a card reader may not even exist.

Underground Shopping Is Especially Useful on Bad-Weather Days

This might be the single most practical reason to build underground shopping into your itinerary at all.

Rainy afternoon? Go underground. Freezing winter morning? Same answer. Peak summer humidity? You already know where this is going.

Seoul's connected indoor network turns a weather problem into a shopping opportunity instead of a wasted afternoon. Checking conditions ahead of time still helps you decide when to plan an outdoor day versus an underground one.

If rain or extreme heat changes your plans, our guide to Korea weather apps, rain timing, and fine dust can help you decide when an underground shopping day makes more sense.

Common Mistakes Foreign Visitors Make

Assuming Every Underground Mall Works Like COEX

COEX is the exception, not the rule. Most of Seoul's underground shopping areas run on the merchant-stall model, without COEX's corporate customer service layer behind it.

Expecting a Refund Without a Receipt

A cash purchase at a small stall often comes with no receipt at all. Without one, there's no transaction on record to reverse, no matter how reasonable the request feels.

Not Confirming the Exit Number in Advance

Express Bus Terminal Station alone connects three subway lines. Walking out the wrong exit can put you a long, confusing walk away from where you actually meant to go.

Treating It as a Five-Minute Stop

Goto Mall's two corridors stretch nearly a kilometer combined. Budgeting fifteen minutes usually means turning around before you've seen half of it.

Getting Too Focused on the Lowest Price

A low price tag isn't automatically a good purchase. Check the stitching, the sizing, and whether the stall has any return policy at all before you commit.

Practical Tips Before You Go

Wear comfortable shoes. These corridors involve more walking than they look like from the map.
Keep your entry station and exit number handy the entire time you're browsing.
Bring both cash and card. Neither one alone covers every underground mall in Seoul.
Check tax refund thresholds ahead of time if COEX is on your list, since the process runs through the mall's own kiosks.
Don't expect English signage everywhere outside COEX. A translation app goes a lot further at Goto Mall or Jonggak.
Compare before you buy. A similar item at a better price is often just a few stalls away.
Check current hours before a special trip, especially for the smaller centers like Sogong, where listings aren't always consistent.
If you find a small shop with limited English signage, knowing how to use Papago in Korea can make questions about prices, sizes, and products much easier.

A Simple Strategy for First-Time Visitors

You don't need to hit all six. Pick the one that actually fits your day.

Affordable fashion and browsing: Start with Goto Mall.
Trendy Gangnam shopping: Try the Gangnam Station underground shopping center.
Already in Myeongdong: Walk through the Myeongdong Underground Shopping Center.
Traditional goods and downtown connections: Add Sogong.
Heading to Insadong: Stop by Jonggak on the way.
A polished, modern shopping day: Choose COEX.

Summary

Seoul's underground shopping malls aren't one category, even though search results tend to lump them together. COEX runs like the mall you already know how to shop at, card-friendly and centrally managed. Goto Mall, Gangnam Station, Myeongdong, Sogong, and Jonggak run more like old-fashioned markets that happen to sit beneath a subway station, cash-friendly, stall by stall, with no single company standing behind every purchase.

Neither model is better than the other. They're built for different kinds of shopping trips, and once you know which one you've walked into, the rest of it makes a lot more sense.

Editorial note: Store counts, operating hours, and tax refund procedures at underground shopping centers can change without much notice, since most stalls are independently run rather than centrally managed.

Where hours could not be consistently confirmed across sources, that uncertainty is noted directly in the text. When a specific store gives different information in person, follow what that store tells you.
