Grocery shopping in Korea as a foreigner is an adventure — Korean supermarkets are enormous, traditional markets are a sensory overload, and online delivery via Coupang can have fresh produce at your door in hours. Understanding where to shop, what to buy, and what things actually cost will transform your daily life in Seoul. This guide covers every grocery shopping option available to foreign students and long-stay visitors in Korea, from Emart and Lotte Mart to Namdaemun Market and Coupang Rocket Fresh.

Major Supermarket Chains in Korea

Emart (이마트)

Emart is Korea's largest hypermarket chain, with over 150 stores nationwide. Most large Emart stores are open 10:00–23:00 daily (some close on the second and fourth Sunday of the month). Emart is excellent for bulk buying, household goods, clothing, and groceries. Prices are reasonable, and the store layout is similar to Costco or Walmart — large, organised sections for fresh produce, meat, fish, dairy, and packaged goods. An Emart store is located in major areas including Mapo, Songpa, Nowon, and Seongdong in Seoul.

Typical prices at Emart: 1kg of Korean rice (쌀) ~3,500–4,500 KRW, 500ml milk ~2,200 KRW, 10 eggs ~3,000–3,500 KRW, chicken breast (100g) ~1,800 KRW.

Lotte Mart (롯데마트)

Lotte Mart is Emart's main competitor and is similarly large-format. Good Lotte Mart locations in Seoul include Mapo, Jamsil, Yeongdeungpo, and Guro. Lotte Mart often has excellent fresh produce sections and competitive prices on Korean pantry staples. They frequently run sale events, especially around Korean holidays (Chuseok and Lunar New Year).

Homeplus (홈플러스)

Homeplus is another large Korean supermarket chain, originally founded as a Tesco joint venture. It is slightly more focused on international food products than Emart, making it a good option for foreigners looking for imported cheese, European snacks, or specialty ingredients. Locations include Mapo, Gangseo, and Seocho in Seoul.

GS Supermarkets and SSG (쓱닷컴)

GS Retail operates GS Supermarkets (smaller neighbourhood stores) and GS25 convenience stores throughout Seoul. SSG.com (pronounced "sseuk") is Shinsegae/Emart's premium online grocery delivery service, offering same-day delivery on fresh produce and specialty items. SSG is slightly more expensive than regular Emart but stocks higher-quality imported products.

Online Grocery Shopping: Coupang Rocket Fresh

Coupang's Rocket Fresh (로켓프레시) service delivers fresh groceries — vegetables, fruit, meat, dairy, and prepared foods — with next-day or same-day delivery to most Seoul addresses. Orders placed before midnight arrive the following morning before 7:00 AM. This is genuinely one of the best grocery delivery systems in the world and beloved by Seoul residents who prefer shopping from home.

A Coupang Rocket WOW membership (7,890 KRW/month) gives you free shipping on Rocket Fresh orders over a certain threshold. Without membership, Rocket Fresh delivery is 3,000 KRW per order. The app is primarily in Korean but Google Lens can translate the screen — and after a few orders you will memorise the layout quickly.

What to Buy on Coupang

Rice (쌀), ramen, ramyeon, kimchi, gochujang, doenjang (soybean paste)
Eggs, tofu, seasonal vegetables (Korean spinach, perilla leaves, green onion)
Fruit: Korean pears (배), mandarins (귤), strawberries (딸기) in season
Frozen dumplings (만두), tteok (rice cakes), and pre-made side dishes (반찬)
Beverages: sikhye (sweet rice drink), barley tea (보리차), kombucha, soju, beer

Traditional Markets: The Best Way to Shop Fresh

Gwangjang Market (광장시장)

Gwangjang Market in Jongno-gu is one of Seoul's oldest and most famous traditional markets, open since 1905. It is famous for street food (bindaetteok/mung bean pancakes, mayak gimbap, yukhoe/raw beef), but it also has dozens of stalls selling fresh vegetables, dried goods, spices, and Korean pantry staples at very competitive prices. Nearest subway: Jongno 5-ga (Line 1). Open daily 09:00–23:00.

Namdaemun Market (남대문시장)

Namdaemun Market (near City Hall, Line 4) is one of Korea's largest traditional markets and a great place to buy dried fish, nuts, spices, Korean tea, and fresh produce at wholesale-adjacent prices. It is also excellent for clothing, kitchenware, and household goods. The market operates around the clock (24 hours) with different sections active at different times.

Noryangjin Fish Market (노량진수산시장)

Noryangjin (Line 1, Noryangjin Station) is Seoul's largest wholesale fish and seafood market. It is open 24 hours for wholesale trade, with the main retail hours from 06:00 onwards. You can buy live seafood directly from vendors at very low prices, then have it prepared at one of the restaurants upstairs for a cooking fee of 10,000–15,000 KRW. Whole live crab (꽃게) from 15,000 KRW, live abalone (전복) from 3,000 KRW each.

Specialty and International Grocery Stores

If you miss food from home, Seoul has excellent options for international groceries:

Itaewon Global Food: Located in Itaewon, this cluster of import shops stocks halal meats, Western cheeses, American snacks, Middle Eastern spices, and more
Dongdaemun Foreign Food Market: Near Dongdaemun History & Culture Park (Line 2/4/5), this market has Chinese, Southeast Asian, and Central Asian ingredients
CostCo (코스트코): Locations in Yangjae and Yangpyong — Costco Korea stocks many imported Western products alongside bulk Korean staples
올가 (ORGA): Organic and natural food stores similar to Whole Foods, with locations near Sinchon and Gangnam

Typical Monthly Grocery Budget in Seoul

For a foreign student cooking at home most days in Seoul, expect to spend:

Cooking most meals at home: 200,000–350,000 KRW/month
Mix of home cooking and eating out: 400,000–600,000 KRW/month on food total
Mostly eating out or delivery: 600,000–900,000 KRW/month

Korean dining out is relatively affordable — university cafeteria meals (학식) cost 4,000–6,000 KRW, convenience store meals (편의점 식사) 3,000–5,000 KRW, and standard local restaurant meals 8,000–13,000 KRW. Cooking Korean food at home using ingredients from traditional markets is the cheapest option of all.
