Gangnamru is a Chinese restaurant in Seoul that serves jjajangmyeon and jjamppong. The jjamppong broth is made with Hanwoo beef stock, giving it a deep flavor and a moderate charred note, and a white jjamppong is also available. The jjamppong is clean and light, with a spice level that is usually on the hot side. At lunchtime, customers crowd in, so wait times for dishes run long and table service is slow.
