I love LUNA and I don't even dance very much (unless I'm hammered).
It's an eclectic group of party people, from hipsters to sexy ladies in dresses to guys with huuuuge beards. I like the diversity. I've never once had a problem with a douchebag at LUNA, and I've been going for 2-3 years. The drink specials are legit (free drinks on Wednesdays, hell yes) and the $2 You-Call-Its are amazing. The music is also pretty solid -- mostly electronic/techno with some rap thrown in here and there.
The place is down to earth and I like that. I also like that I can smoke a cigarette and not get my beer/whiskey taken by some overzealous employee. If you want to avoid the frat boys and ditzy girls you'd see at most spots on Main Street, go to LUNA.
