Love this place. Every time I'm up in the Phoenix area I try and stop in for one meal.
Fish is always fresh and flavorful. Service is pretty good. The owner seats you but doesn't do much after that, and he's pretty quiet; not rude but no super friendly. Two young guys are the sushi chefs.
The rolls are pretty good, but what does it for me here is the sushi. They also have a really good bbq beef tongue.
If you happen to go between 5-7pm, they have a happy hour. Some drinks, sushi, rolls, and appetizers at a discount. Not a bad deal. I've happened to dine twice during happy hour and ordered about half my meal off the HH menu and half off the regular menu. Some fishes I crave aren't on the HH menu.
The atmosphere is laid back, and I've always gone dressed casual. Some people do get dressed up but it's not necessary.
Try this place, it's legit!
