Kanesaka, Ginza 鮨かねさか銀座
I once made the mistake of joking to my dining partner that there's not much to making sushi as you just have to get some fresh fish and cut it up. Well, I am forced to admit that there is sushi and there is sushi. Kanesaka, located in a basement in Ginza, is the second type.
It's an extremely expensive restaurant, but for an unforgettable flavour and experience I would say that you should stretch yourself at least once. Although everything was excellent, the eel, the chu-toro and the uni were simply stunning and would justify a visit just for those.
