I love this place. I prefer it's ambience over Haruki anyday. The waitstaff is very friendly and accomodating. The chef will come out to see you if there is a slight problem. The decor is beautiful and simple. The sushi here is the best I've had in Providence so far. The menu has a very good selection of food as well as a good selection of sushi. In the appetizers, try the fried tofu in sauce and green onion. When I go there the crowd is quiet, sophisticated and casual. Business people, visiting foreigners and students from the grad school down the street. It accomdates large parties of 4 or more. If you are bringing a lot of people, I would make reservations, but you don't need to.
Pros: Food, atmosphere, service and over all experience.
Cons: If you want to be impressed, like with a laser light show or something, the elegant simplicity wil be lost upon you.
