Wanggeumseong Isu Station is a Chinese restaurant that moved from Gubanpo to Isu Station. It serves jjajangmyeon, jjamppong, white jjamppong, and tangsuyuk, with the jjajang and jjamppong prepared to be neither salty nor spicy. It opened in 1979 and relocated from Gubanpo, and it has many rooms available for use with a reservation. The tangsuyuk comes mixed in sauce, so it is only lightly crispy and the meat is on the chewy side.
