Hangang Banjeom is a Chinese restaurant on the third floor of Insadong-gil in Jongno-gu, Seoul, serving jjajangmyeon, jjamppong, and tangsuyuk. Jjajangmyeon and tangsuyuk can be ordered together as a set. Tables range from two-person seating to tables that seat more than ten. The floor is slippery, and food residue or stickiness remains on the dishes and cups, indicating poor hygiene management.
