Eat here. I could stop the review with those two words but I'll add a bit more color. This is hands down the best sushi spot in Phoenix. I've tried way too many of them. After a while I got to know the owners, Kenny and Vivian, and they're very nice and accommodating. Kenny was always willing to make a special off-menu dish (I never asked for one if they were swamped) and they sometimes have specials you won't get in most places, like the time they had a fresh sea urchin (delicious). Also, get the fresh (real) wasabi. You won't regret it.
Alas my time in Phoenix ended (a while ago - somehow I forgot to post this review) and this spot is what I miss most. If you see Kenny and Vivian, tell them I said hello.
