Onsuban Chungmuro is a Korean restaurant near Chungmuro Station and the entrance to Namsangol Hanok Village, serving gogi gukbap and beef pho. Its signature dishes are the mixed onmyeon and onban, which contain chadol yangji, tendon, and arongsatae in a clear, deep broth like gomtang. Orders are placed at a kiosk at the entrance, and seating is at a U-shaped counter around a central open kitchen, where rice or noodles can be refilled for free. The indoor space has around ten seats, is cramped, and tends to be hot in summer.
