I can say for certain this is the best sushi I've had in Madison, but it's also the only sushi I've had here. Compared to other sushi I've had in the Midwest it's good. I wasn't wowed by the flavors or how well they were rolled. Also note I didn't try the sashimi. The spicy salmon roll was probably the best. It was very fresh and had a good blend of spices no spices were to bold or over powering. The spicy tuna was interesting, it had a strong chili pepper taste. The tempura shrimp was lacking all around. I've tried several other rolls, I don't remember each one, but some of them were very good, but most only good.
Overall it's is good I'd go again, but it is more expensive than I'd expect for Madison and for the quality. I've had better for less in Milwaukee and Chicago. It can also be very hard to get a table so make a reservation. Fortunately, I live across the street so if there's an hour wait I can just go home and come back or get it to go, but if you don't want to wait you need a reservation, even for lunch.
