Excellent place for concerts or etc. There doesn't seem to be a bad seat in the place. Even the higher up cheap seats seem to have a pretty good view (I haven't sat there, but it didn't look bad)
I've seen a few concerts and comedy shows here so far and it's one of my favorite venues. There are two bars (although the side bar isn't always open)
One concern I have is there is only one set of stairs/elevator to get in and out. That sounds like a fire code, but what do I know? I'm sure it's fine and only a few people would be trampled to death...
Sound quality is very good. I have no desire to ever sit in GA, so my preference is definitely the middle section. I personally like the side, but I think all of you should sit in the center... you know to leave those side tickets available for me J
