On Gimpo’s Domestic 4F food court, this stand does udon fast
Up on the 4F restaurant level in the Domestic Terminal, Japanese Noodle Bar keeps things simple: bowls of udon, a few toppings, and quick counter service. It’s inside security, so you can eat after check-in and still be near the domestic gates. The place runs on a straight 11:00–20:00 schedule, so don’t count on a late-night bowl after the last flights.
Prices sit in the ₩10,000–₩12,000 range, with the kimchi udon set around ₩11,000. That combo gives you a hot noodle bowl plus two pieces of inari sushi, which one Trip.com reviewer said was enough for a full meal before a domestic departure. Broth leans light and salty rather than heavy, which helps if you’ve got more flying after Gimpo and don’t want a big rice set weighing you down.
Menus lean udon-first: plain, kimchi, and a couple of tempura or fried-topping options you can spot on the overhead boards. Most bowls land in under 10 minutes, even when the 4F restaurant area fills up around the 12:00–13:00 and 18:00–19:00 peaks. Compared with the bulkier Korean set menus on the same floor, this is the quick single-tray option that still feels like a real meal.
Regulars on Korean sites talk about going straight for the udon sets with inari sushi so everything comes on one tray, then heading to the gate with time to spare. With a rating around 3 out of 5, it’s more “reliable stall” than destination noodle shop, but at a $ price tier it beats grabbing only chips and coffee downstairs. One tip: order, take your receipt, then hover near the pick-up counter; they call numbers fast, and missing yours can add an annoying extra few minutes.
