This place is absolutely brilliant.
As mentioned, if you are going for "authenticity", go elsewhere. If you want real authenticity, stop looking in an American city. This restaurant is another great take on the make-as-you-like meals. If you want a small maki, again, this is not the place for you. However, for a roll that functions as a small sandwich, this is wonderful!
I very much recommend, and I only wish they had vegetable tempura!
