I first heard of this place from postings on this board (thanks, Clare K) and I have tried it twice now -- it has only been open three weeks. It was quite good both times.
The big eye tuna, yellowtail and red snapper sushi have been particularly delicious on my two visits, and last night my wife said the toro was the best she'd ever had. The crab ngiri and crab hand rolls have disappointed a little, but overall I have been very pleased at the quality of the fish, the selection and the service.
It's a cut below Nozawa and probably Sushi Gen, too, but it's not nearly as crowded as either one, and you have more elbow room to eat. I would rank it just above Sushi Go 55 and R23 downtown, in terms of the quality of the sushi.
It's a great addition to the sushi scene downtown.
