Ppongsabu is a Chinese restaurant in an alley near Gangnam-gu Office Station, serving jjamppong and jjajangmyeon. The jjamppong contains plenty of seafood such as mussels and clams, the broth is clean-tasting, and customers also order chapsal tangsuyuk alongside it. At lunchtime a queue forms from office workers in the surrounding buildings, and the jjajangmyeon can be ordered with gochutgaru added. The seating is tightly packed, so the room feels cramped at lunch.
