Okinawa Soba Den is a small noodle shop near Kokusai Street that serves Okinawa soba and mazesoba. The soba comes in a clear broth with katsuobushi aroma, topped with chewy noodles and samgyeopsal. The mazesoba is mixed with vinegar before eating. The shop stays open late, so customers come after drinking, and because it is small with few seats, there is a wait when it gets crowded.
