Korean convenience stores

A different category of shop, not a smaller supermarket.

Korean convenience stores cook, host, deliver and run their own product lines. Chains hold exclusives you cannot buy anywhere else, prices move with promotions, and the stock rotates fast enough that a guide written last year is describing a different shelf. Here is what is on it now.

The four chains, and what separates them

There is no single “number one” — GS25 leads on revenue and CU on store count, which is why Korean coverage always has to say which measure it means. For a visitor the practical difference is the exclusives.

ChainKnown forExclusive worth crossing the road forWhere it stands
GS25지에스25Widest coverage outside big cities; strong own-brand drinksYellow-cheese snack line, including the Haitai crispRevenue leader — about ₩8.67 trillion in 2024

Business figures are 2024 full-year, from Korean business press. Store counts across the four chains fell by about 1,600 that year.

What it costs right now

Checked August 2026

Every figure below links to the article it was verified in. Korean convenience stores use open pricing, so individual stores vary and promotions are constant — treat these as the band, not the till receipt.

The products worth knowing

Each of these is a specific thing on a specific shelf, with the story behind it.

A Korean triangle gimbap in its wrapper.

Samgak kimbap

The wrapper is an engineering solution. Open it in the wrong order and it falls apart.

Viyott, a Korean convenience store yoghurt snack.

Viyott

The yoghurt with a topping lid, and why the mixing ritual is the product.

Carbo Buldak, the creamy spicy Korean instant noodle.

Carbo Buldak

How a creamy version of a fire-noodle became the export that carried the brand.

The small bottles

The two brown bottles beside the till, and why one of them is legally a drug.

A bottle of Bacchus F, the convenience store version.

Bacchus D vs F

Taurine above 1,000mg makes it a pharmacy-only quasi-drug. The smaller bottle is the stronger one.

A bottle of Vita 500, the Korean vitamin drink.

Vita 500

Registered as a drink rather than a quasi-drug, which put it on shelves ten years before Bacchus.

How the shop itself works

The machines, the discount clock, and the parts of the format that are not about food.

The automated store

Ramen machines, self-checkout and robots — what you are expected to operate yourself.

Taking it home

Most of what makes a Korean convenience store good does not travel — the chilled cream bread, the meal trays and the machine-cooked noodles are all things you have to be standing there for. The packaged snacks do travel, and they are cheaper at a mart than at a convenience store, which is the single most avoidable overspend for visitors.
