We found this on Yelp and it had good reviews there (only in Japanese), thought it was worth a try as it was close to our hotel. None of the staff had any English and no English menu, but we managed to get a first course of sashimi ordered. They really didn't seem to know what to make of us; fortunately, they dragooned one of their guests from the back dining room who had some English and we made progress with further courses. Chef finally asked us how we had found his place as foreign tourists don't come here. By the end of the meal, he was clearly pleased that we had so much enjoyed his cooking (including some fabulous miitake mushrooms done in tempura, an omelette with fermented soy beans, and a churashi don), and he presented us with a framed print of the Nebuta as a souvenir. Truly delightful and hospitable people here!
