As far as my experience goes, there were definite aspects that needed vast improvement. But this is the place to go for the value of seeing an artist you love, so long as it isn't overcrowded(the night I went it was perfect, not claustrophobic like I've heard about other nights.) Just keep this in mind when going, is it an high profile artist? Then it will be miserably crowded like others complain of. I went and saw a kickbutt artist who's gaining a lot of traction and if it were anymore crowded it would've been too much but it was just right.
Based on my experience I would most likely go again if there's an artist I wanna see....but DANG FIX YOUR FOOD! The fries were too thinly sliced I couldn't eat them without pain from crunching down so hard, and after waiting 40 minutes for them, well, that's kinda pushing it. The people staffed there were very helpful and nice at least. It was just the fries that was the main negative for me.
Oh! And the ventilation was just fine, I understand that's been a concern other nights, but I think that might have to do with the fact it was a cooler night and tickets weren't oversold. So anyone hesitant on going, just read the reviews and guesstimate what kind of experience to expect based on what other reviewers said. From there determine if the guesstimated experience is something you want/worth it for you. I lucked out.
