Rohp what is your problem with the owner? I have been many times and enjoyed many a pleasant and interesting conversation with the owner, who strikes me as one of the most genuine and friendly restaurant owners in Tokyo (or anywhere). It seems to me that you are criticising him without due cause, as I believe he runs this restaurant for all the right reasons. Please consider that if he were just wanting a fast buck he would sell alcohol (which is how most restaurants in Japan make most of their money) but he doesn't because he stays true to his Jain principles. There's not much to dislike about this restaurant, or its owner.
