₩11,000 kimchi udon sets on Domestic 4F
On the 4th floor of Gimpo’s Domestic Terminal restaurant zone, Kimbap Cheonguk feels closer to a neighborhood “gimbap shop” than an airport brand. It runs roughly 06:30–20:00, so you can get a hot bowl and kimbap before most Korean domestic departures and after the evening rush calms down.
A Trip.com reviewer called out the kimchi udon set at about ₩11,000, which comes with two pieces of fried tofu sushi (inari). That set is enough for a full pre‑flight meal without creeping over a budget‑friendly ₩15,000. Expect basic plastic trays, counter ordering, and food on the table in under 5–10 minutes when the 4F area isn’t slammed.
The menu sticks to airport‑priced but still cheap Korean diner staples: kimbap rolls around the ₩4,000–₩6,000 mark, soup and noodle bowls in the ₩8,000–₩11,000 range, and simple set combinations. Rating sits around a 3/5, which tracks with “tastes like a normal city branch” rather than a special destination. Portion sizes read as commuter‑friendly: enough to fill you up, not a marathon meal.
Regulars heading out of Domestic time it so they hit the 4F restaurant area about 5–10 minutes before boarding, order the kimchi udon set or a quick kimbap plus soup, eat fast, and walk straight down to security and the gates. Turnover is quick, so tables open frequently even during the morning bank around 08:00–09:00.
Watch your clock: the 4th floor sits above the check‑in hall, and you still need a few minutes to get back to security and down to your domestic gate. Last practical tip: if you’re cutting it close, order one kimbap roll to go for under ₩6,000 and eat it at the gate instead of gambling on a slower sit‑down set.
