Sopyeongru is a small Chinese restaurant on the second floor of Hyundai Outlet in Gangseo-gu, Seoul, serving jjajangmyeon and jjamppong. It is closer to Yangcheon Hyanggyo Station than to Balsan Station. The jjamppong contains many ingredients, and the guobaorou can be ordered with the sauce on the side. A line forms at lunchtime and the store is busy during main hours, with a small space and few tables making it crowded.
