One of the best restaurant experiences we've every had, and we've been to a lot of restaurants over the years. Truly authentic as it's where the locals will go. This is not a tourist trap and it's worth the effort to find your way to this place. The sushi is superb but what makes the experience really unique are the couple who own and welcome you into there establishment. The chef is fun and extremely interactive with the customers and his wife provide impeccable service throughout the meal. If you are anywhere near Shinagawa this is a place you do not want to miss. Enjoy.
