Kim Changyong's Onggolmyeon is a noodle shop in Nowon-gu, Seoul, selling saengmyeon guksu, jeyuk deopbap, and napjak mandu. It sits directly in front of Exit 2 of Nowon Station on Line 4, and in summer it also serves kimchi mari guksu with soft, long fresh noodles in a broth that is not spicy. The hall has about five tables and a loft-like space on the second floor, and many customers eat alone. The shop is small and the building is old.
