I am a huge Suns fan, and being from LA, born and raised, I was excited to go watch their first home game of the 09-10 season.
There's plenty of reasonably priced places to park near the center and all that look pretty legit (none of the shady business you see in LA). From outside it looked pretty small, but once you step inside it's a whole different story. Wide hallways that are properly marked telling you where you are make it easy to find your way around.
Compared to Staples the place is "tiny," but because it is every seat in the house has a great view. No such thing as nose bleeds here. If you're in town to watch a Suns game or another event check it out.
