Matdol Son Kalguksu sits between Songjeong Station and Osiria Station, serving kalguksu, sujebi and gimbap. The noodles are made in-house and served in an anchovy broth with house-made kimchi and onion soy sauce. By 11:40 few seats are left, and around noon a line of waiting customers forms; there is a parking lot behind the shop and a self-service condiment bar. Each person must order one bowl of kalguksu.
