The only place I've ever had better sushi was at the fish market in Tokyo. Admittedly, I'm not a profesional sushi critic, just an armchair fan, but that's my experience as a ""civilian"".
Fish so fresh it melts in your mouth, warmed rice that (to me) enhances the flavor, and fresh (not fake?) wasabi. Omakase is good, but if you're in a party smaller than 4, go with a-la-carte and order your favorites. Absolutely recommend. Heaven, heaven, heaven....!
