Filmore is a great music venue for the fact that the stage is up so high-- this makes it near impossible to have a bad seat in the house. I've been to several shows at the Filmore and even a few events. I like that there is more than just one bar (which reduces lines and wait time for libations). I also appreciate that the venue is well-ventilated. I cannot tell you how many shows I've been to where I am DRIPPING sweat. I do not believe you will have this problem at The Fillmore. The place is appropriately cooled for the expected amount of patrons at a concert.
My only beef is that the drinks are WAY too expensive. I mean come on, we are already paying the fee for the tickets + the 'processing fees,' there really is no reason to pay 11 bucks for a house vodka (aristocrat) and tonic. That's ridiculous. My advise, go over to VBGB for your cocktails before you go to the show and then stick to an overpriced Bud Light for the concert.
