Miso happy! This is the best sushi I've had in Phoenix. By far. Hands down.
Best miso soup - ever. I had their salmon oyster roll thing - raw oyster wrapped in a piece of salmon with salmon roe on top. It was divine! (I fantasize about this, seriously.) Their soft shell crab is... wow. Melt in your mouth perfection.
They don't do happy hour, but the prices end up being very reasonable for what you get. I tried their baby yellow tail and a huge piece of clam. Tasty!
Yasu is small, so get there early. The place can fill up quick! I love the atmosphere inside. The service is superb and the staff is uber-friendly. When we walked in, the guy behind the bar waved at us.
If you don't live nearby, it's ok. The sushi is definitely worth the drive. And if you live close-by, I hate you. (Just kidding. Or am I?)
