Gate-side snacks without markups
Prices at Gimpo’s 7-Eleven track local street stores, so you’re not paying “airport tax” on basics like onigiri, kimbap, and bottled drinks. You’ll find this branch in the passenger area at GMP (check signage for the nearest 7-Eleven to your International or Domestic gate). Expect cold drinks, cup noodles, instant coffee packets, and standard convenience-store sweets stacked floor to ceiling.
Most items sit under ₩5,000, including triangle kimbap, small sandwiches, and canned coffee. That beats most café or fast-food combos in the International terminal by a wide margin. If you want a quick breakfast before an 08:00 departure, the pre-packed bread and yogurt section usually does the job in under two minutes, self-checkout included where installed.
Hours typically run from early morning into late evening, roughly tracking the first and last flight banks on both Domestic and International sides. That makes 7-Eleven one of the more reliable spots for a 06:30 water bottle or a 22:00 snack after a delayed flight. Alcohol sales follow local rules, so expect beer and soju in the fridges during permitted hours.
Watch out for hot foods that have been sitting too long in the warmer; check timestamps on items like corn dogs and fried snacks, especially at quieter midday periods between bank peaks. Instant noodles are a safer play: grab a cup under ₩2,500, use the hot water station, and eat at nearby public seating rather than crowding the entrance.
Quick tip: buy a couple of 500 ml waters or teas here before boarding; on many short domestic hops out of GMP, in-flight drink service is brief and a single cup doesn’t last a full 60–70 minute block gate to gate.
