Kkweng Kalguksu is an old restaurant in the market alley between Wangsimni Station and Sangwangsimni in Seongdong-gu, Seoul, serving duck meat and pheasant kalguksu. Ordering the grilled duck brings a small serving of pheasant kalguksu as a finish, eaten with three kinds of kimchi. The owner, past 70, cooks the food and has sold duck meat and pheasant kalguksu here for 28 years. Parking is inconvenient.
