A lot of parties are held here. It's a pretty big place but there's a lot of different rooms/sections in Spiros. Make sure you know where the parties are at because I remember walking into the wrong side and felt very intimidated. There's quite a bit of lounge area too. Just a heads up, on some nights, there's a person in the bathroom that gives you paper towels and soap and tries to sell you stuff. Every once in a while I tip them.
