Is there such an animal??
a king of the hill #1 place in Tokyo for sushi, money no object??
Yet, you will have to fight it !! After my last month 100 pieces (can I make star ?), the last best one will be in my opinion Kozasa, but I prefer to not make many comments on a 1st impression face !!!
The sushi that respond to my phone call (=I did) 'i am hungry!!!' is Sukiyabashi Jiro. Even I am alone, and the 20 pieces will be surely not enough, Ono-San will give me the apart from menu pieces with protection, dignity and no wait..yes this is my best one !!!
It is a living experience, so my thoughts will change month by month.
