Tongkeun Kalguksu is a kalguksu shop in the middle of Suwon Nammun Market. It serves hand-kneaded noodles rolled with a rolling pin as kalguksu and janchi guksu, and a double portion is available. Kimchi and water are self-service, and orders are paid in cash in advance, so there can be a wait depending on the time. Table spacing is narrow and the service is disorganized.
