Yen has amazing sushi. I would say that they have the best sushi in AZ. You have to try it to see how amazing it is. The service is great and I feel like I just stepped into Japan. The whole sushi experience is very authentic and perfect place to hang out with friends or take a date :D
There is only one thing I don't like. Sometimes it get's to busy so make sure to get there early (around 7 P.M) if you want to be seated right away.
