Chakhan Jjajang is a Chinese restaurant in the back-street commercial area behind the Hyundai apartment blocks north of Seongsu Station, serving jjajangmyeon and jjamppong. The jjajangmyeon is made in an old-style flavour, and the place is easy to eat at alone. At lunchtime, office workers from nearby come in, and food comes out almost immediately after ordering. The taste is ordinary.
