I've been a few times, and overall the atmosphere has been very chill without too many rowdy ASU students.
Service in the dining area was a little off-- orders were forgotten--but the place is new enough so I understand.
The food is delicious, they serve Orion, and have a great selection of sake and are very knowledgeable and eager to let you sample, especially if you sit at the bar.
The owners and staff are all really cool and I love that I can go after midnight on the weekends. I just wish it were a bit cheaper.
