Old Flavor Myeongdong Kalguksu is a restaurant in the basement in Seoul that serves kalguksu, mandu-guk, and bibimbap. The kalguksu comes with soft noodles in a clean broth and one large mandu, eaten with geotjeori and dadaegi. Noodles and a bowl of rice can be added for free. Because the dining room is underground, the old-style chairs are placed close together front to back.
