Somanan Kalguksu is a noodle shop between Gangdong Station and Gil-dong Station that serves sagol kalguksu, jang kalguksu, and mandu guk. The signature dish is sagol kalguksu: thick, rich beef bone broth with chewy noodles and beef topping, eaten with kimchi, scallions, dadegi, and pepper added to taste. The shop has been open for 30 years, and rice is refilled for free from the rice container. During the lunch peak, orders require waiting.
