Andongjang is a Chinese restaurant in Singil-dong, Seoul. It serves a set that includes tangsuyuk, jjajang, and jjamppong, and the jjamppong can be changed to samseon for a clean but distinctly unusual flavor. The old establishment has about ten four-person tables and a floor-seating room. The hall dining area, tables, and tableware are in an unclean state.
