It was good. It was very, very good. I particularly recommend the tuna and jalapeno sashimi (and I don't normally eat raw fish, but I wasn't going to pass it up this time) and the cod that comes on a lettuce leaf with a little shredded, toasted phyllo on top.
Our waiter was patient with us, and helped us decide even though we were a bit clueless. The service is fast once you make up your mind about what to eat; and we ordered in waves, which the kitchen was fine with.
The only reason this wasn't a 5-star experience is that the room is small, crowded, dark, and noisy. We were literally reading the menus with the lights from our cellphones. The price of everything probably also weighs into my decision not to give the place 5 stars. For five of us to eat enough not to be starving but not to be totally full either was more than $300, and that includes one drink apiece.
