Sacheonru is a Chinese restaurant near Baengbaeng Sageori in Gangnam, Seoul, serving jjajangmyeon, jjamppong, bokkeumbap and tangsuyuk. In winter it offers gul jjamppong with a smoky wok flavor, and there are weekday menu discounts. At lunch it fills with Gangnam office workers, but the food turnover is fast and groups can eat in a private room. Seating is tight, so the dining room is hectic during lunch hours.
