Between 2.5 to 3 stars.
Service is spotty. Need to ask multiple times for things we need, especially they weren't busy at all at 6pm. Is it fast casual? Not really, but they left a bottle of water which I don't mind. Is it full service? Yes, expecting 20% service fees with the excellent service correspondence to it; but no, it didn't deliver.
Sushi is avg at best. No wasabi between the rice and fish. Rice is not vinegarette. Rice is also mushy. Price is avg, it seems like you get what you paid for.
Definitely better quality than their sister restaurant @ru san's, but still a tad off from being solid 3 or 4 stars.
Will give it one more shot.
