Definitely NOT gluten free. Those leaving reviews saying it is are totally following the fad. I'm celiac and if you ask further questions, they share the fryer, they share the boiled water for both gluten and gf items. The sushi rice, although they never labelled as GF, is most likely made of a vinegar that has some form of wheat to flavor it.
The server was knowledgable when asked these questions, which I'm grateful for, but the only thing I recommend the restaurant is to further educate themselves on the GF designation. They did have GF soy sauce which I was also grateful for.
