Bukchon Son Mandu Bukchon Branch is a small dumpling shop near Anguk Station that serves mandu, mandu-guk, and pi-naengmyeon. The signature items are modum mandu, fried mandu, and galbi mandu, while the pi-naengmyeon comes with a sour, cool broth and noodles that are not tough. The narrow space holds only bar tables, and customers order and pay in advance at a kiosk at the entrance. Portions of mandu are on the small side.
