The number of seats in the restaurant is only six. Six is the maximum. Besides the owner receives only a single booking per day. He used to be the chief-chef in the ANA hotel which is the highest level hotel around here and he returned to his original home to take care of his almost bedridden mother. He decided to open his own restaurant in his hometown and serve one single group a night with all of his skills. His plan was successful and his restaurant became a huge hit. People indulge in tasting the lavish dishes.
The other day, I was able to have dinner there because of a sudden cancellation, so I immediately booked it for dinner. When we started talking about the porcelain during dinner, the owner brought out some old sake flasks and cups which had been produced 100 years ago. The conversation with such professionals is always fun.
