Gahwa Banjeom is a neighborhood Chinese restaurant in the basement of a commercial building in Bukaahyeon-dong, Seodaemun-gu, Seoul, near Exit 1 of Ahyeon Station. It serves jjajangmyeon, tangsuyuk, and jjamppong, and its jaengban jjajang can be ordered as a single portion. The kitchen cooks each order after it is placed, so the noodles come out soft, and the restaurant does not deliver. The tangsuyuk has a thick batter and a small amount of meat.
