Ossi Kalguksu is a kalguksu restaurant in Daejeon that serves hand-cut noodles, mulchong clam soup, and seafood pajeon. The noodles come in a rich clam broth and are served with spicy geotjeori kimchi, while the mulchong is boiled with cheongyang chili peppers for a hot, sharp finish. On weekend mornings, a 10:45 opening still meant a 45-minute wait, and the restaurant has a second-floor waiting area and two-person booth seats. The waiting space has poor air conditioning and is uncomfortable, making long waits difficult.
