They do it right here. That's pretty much all you need to know. The fish is exquisitely fresh, and while the price for a meal can get up there if you're ordering a slew of nigiri it's worth it! I'd much rather pay more for something that I know is fresh than go to some place with conveyer belt sushi serving crap. I also like the fact that the sushi chefs are Japanese which at least creates the illusion that they know what they're doing more than someone who had on the job training in Arizona.
