When I rate a sushi place, first and foremost importance in my criteria is the fish itself. Everything else falls into palace after that. This is where Hana excels. The fish is extremely fresh and well cut. Hamachi sashimi is about as good as I've had in AZ. I throughly enjoyed the sashimi salad as well - tons of fresh fish mixed in with nice greens and tasty dressing.
As for everything else, service is good enough, pace of kitchen is satisfactory. Nothing mind blowing here, but all good enough to keep coming back. Waitstaff is friendly. They hurry you a bit sometimes but it does get busy often so it's somewhat understandable.
Overall a great place for fresh quality sushi and the byob is great as you can save the markup on a great bottle of sake or wine.
Sushi: excellent
Service: friendly, satisfactory
Ambiance: neighborhood joint. Nothing fancy, not a dump though
Price: very fair for some stuff, a bit overpriced for others.
