Many restaurants near our hostel closes by 7pm and this was the only one within walking distance that opens past 7pm. They have a section of teppanyaki where the food is prepared in front of you. But we sat at the other side and ordered the chanko nabe (which is basically the food sumo wrestlers eat!). The thought of having hot piping soup on a cold day was the best decision we made. The nabe was super tasty and my husband who's not a fan of soup, drank every last drop. The service was a little slow coz the restaurant was full house but we didn't mind. The staff spoke decent english so we could communicate easily without worrying if we were misunderstood.
