4F crowds upstairs? Burger King on 3F becomes the backup plan.
This Burger King sits airside in Gimpo International, on the 3rd floor near the International security checkpoints, and tends to catch people who give up on the Korean restaurants one level above. Prices run typical for the chain: expect about ₩6,000–₩8,000 for a basic Whopper set and closer to ₩9,000–₩10,000 if you add extra patties or specialty items.
Hours usually mirror the main international departure bank, roughly 07:00 until around the last evening flights, so it works for both morning and after-work departures. Seating is tight compared with the 4F Korean spots, and you’re close enough to the concourse that you can keep an eye on boarding screens for International gates 1–6 without leaving your tray.
Food is exactly what you expect from a low-tier airport Burger King with a 2-star vibe: Whopper, Double Whopper, Chicken Whopper, standard fries, and fountain drinks. Freshness swings a bit; at off-peak times (midday between the 11:00 and 16:00 banks) burgers can sit a few minutes in the chute. If you care about heat, ask them to make the Whopper fresh; it only adds about 3–5 minutes.
Lines spike 30–45 minutes before evening international departures when the 4F noodle and BBQ places hit 20–30 minute waits. Here, you’re usually in and out in under 10 minutes even when the queue spills into the corridor. Vegetarian options are minimal: you’re basically looking at fries, onion rings if stocked, and drinks; there’s no separate veggie burger on the regular Gimpo board.
Practical tip: check 4F first; if every Korean place quotes a 25-minute wait and your flight from Gimpo International boards in under 45 minutes, drop back to this Burger King, grab a Whopper set to go, and eat at the gate seats near your specific departure gate number.
