Very authentic experience. Only one man running the whole restaurant, from catching the fish in the fish tank to cleaning tables, taking orders/payments and cooking. He used a translator device with every customer to explain how to eat the noodles. The soba noodles were 100% buckwheat, so gluten-free, as was the broth. He had an excellent understanding of gluten-free. The food was exceptional would recommend making a reservation, lots of people were turned away as it was full. Only 4 tables thar seat 2 people in the small restaurant.
