3.5 stars, rounded up to 4 on service and value--
Service was quite pleasant: our server magically appeared when we needed water but was completely unobtrusive otherwise. She was also volunteered that we could split our checks without us asking.
The homemade wasabi was really tasty although less spicy than one would typically expect. As for the maki, the fish seemed quite fresh and the menu has a nice variety of cooked, vegetarian, and raw rolls. However, the inside-out rolls had a rather thick layer of rice relative to filling and the rice did not completely cover the nori, which detracted from the aesthetic. That might sound overly picky but part of the appeal of sushi is in its presentation. The vegetable tempura and the Murray Avenue rolls were especially good, but the Squirrel Hill roll was unremarkable.
I'd definitely come here again given the price--$17 after tax and tip for 3 good-sized rolls is a great deal, but if you're looking for perfectly executed sushi, this isn't the place.
