Korean Convenience Store Guide: What to Buy at CU, GS25 and 7-Eleven
Korean convenience stores, called pyeonuijeom, are one of the easiest and cheapest ways for visitors to eat, snack and fix small travel problems. CU, GS25 and 7-Eleven are on almost every block, many are open 24 hours, and most offer free hot water, microwaves and a small seating area. The best things to buy are triangle kimbap, ready meals (dosirak), cup ramen, banana milk and whatever is on the "1+1" or "2+1" deal shelf that week.
The big three: CU, GS25 and 7-Eleven
All three chains sell the same basics, but each has its own private-label snacks, lunch boxes and limited-edition collaborations, which is why Koreans often have a favorite. CU and GS25 are the most common, and 7-Eleven is widespread too. There is no need to hunt for a specific chain: walk into the nearest one and you will find most of the items below. If you see a snack you love, grab it, because seasonal and collaboration items rotate quickly.
What to buy
Triangle kimbap (samgak gimbap)
Rice wrapped in seaweed with a filling such as tuna mayo, spicy pork or bulgogi. The wrapper opens in three steps: pull tab 1 down the middle, then pull the two corners (2 and 3) to the sides. Done right, the seaweed stays crisp.
Dosirak (lunch boxes)
Full meals with rice, meat and side dishes. Heat them in the store microwave, following the time printed on the label.
Cup ramen and "ramen machines"
Cup noodles are filled at the free hot water dispenser. Some stores, especially near tourist areas, have a ramen cooker where you put ramen in a paper bowl and the machine boils it for you.
Drinks
Banana-flavored milk is a classic. Also try sikhye (sweet rice drink), corn silk tea, and Korean fruit sodas. Pouch drinks with a cup of ice (sold in the freezer) are a summer favorite.
Snacks and sweets
Honey butter chips, shrimp crackers, choco pies and seasonal sweets. In November, shelves fill with Pepero sticks for Pepero Day.
Useful services
- T-money: buy a card and top it up at the counter, in cash. Our T-money guide explains how.
- ATMs: many stores have one that accepts foreign cards. Fees vary.
- Everyday items: umbrellas, phone chargers, face masks, basic medicine-adjacent items, toiletries.
Store etiquette
Eat at the indoor tables or outdoor chairs, then clean up: separate leftover soup into the liquid bin, and put cups, cans and plastics in their bins. Do not leave a dirty table behind. At the counter, staff may ask if you need a bag; plastic bags usually cost extra.
Raya from POPORO CITY's rule of thumb: "Check the 1+1 shelf first, then decide what you were craving."

- Bring your own bag to avoid the plastic bag charge.
FAQ

Usually yes. Most have a small counter or tables. Just clean up after yourself.
Can I pay with a foreign credit card?
Yes, at most stores. Keep some cash for T-money top-ups.
Which chain is best?
None is clearly better. The differences are mostly private-label snacks and limited editions, so try all three.
