Go Suns!
US Airways has always been a fantastic venue. I have seen concerts and Suns games here. On my most recent visit I attended the Suns/76ers game.On this particular trip the tickets we had enabled us to eat/drink in Blue Moon Lounge which was fun.
It really doesn't matter where you sit as there are a lot of choices for concessions and the seats are comfortable. Considering the crowd size there is never an overwhelming wait for the ladies room. As others have mentioned, there is no shortage of night life downtown after a game or concert at US airways.
