Gyeongseong Momil is a Japanese restaurant in the alley of Namseong Market near Isu Station in Seoul, serving cold momil, hot momil, and donkatsu. The cold momil is light, and the old-style donkatsu comes as a set with momil or udon. Arriving around 11 a.m. can still mean waiting over an hour from entry to the meal. The dining room is small, so a line forms during meal times.
