Low-key and fun dancing.  fridays are 18+ night which makes for entertaining people watching, in a high school sort of way.  
HOWEVER, if you do not have a driver's license BEWARE!  The ID requirement is driver's license only and even a federally issued passport will not be accepted for entry.  And the staff will not be friendly about it!
Pros:  Low pressure, Fun Music
Cons:  Lewd comments by DJs, Rude ID checkers
