Oldteochon Guksu is a neighborhood noodle shop in Daejeon. It serves myeolchi kalguksu, janchi guksu, and bibim guksu, and also sells gimbap. At 12:30 p.m. on a Saturday the dining room was full, and diners take broth and three kinds of kimchi from a self-service bar. When the lunch crowd arrives at once, orders get mixed up.
