The sushi here is some of the best I've had in Phoenix. I was a fiercely loyal patron of Zen 32 until it closed, and while Hana isn't as upscale as Zen 32 was, I think the food speaks for itself. The fish was fresh and lovely and the squid salad was probably the best I've ever had. I thought it was odd that the edamame was served cold, but everything else was on point.
Hana is super small and it is easy to feel crammed like sardines in there. I like that it's BYOB because it cuts down on the bill. The service was spectacular and prompt even on a very busy Saturday night.
I totally recommend Hana for a casual sushi experience. Excellent food and service.
