I've been to Centro-Fly (Friday and Wednesday), Exit (Friday), Limelight (Friday), Cheetah (Friday), and Vinyl (Friday, Saturday, and Sunday). My favorite by far is Vinyl -- the music is great and the atmosphere is very positive. Of all the places, the people at Vinyl seem the most into the music and each other -- without trying to put on a show. I like Dance Ritual at Centro-Fly Wednesdays, too. It's probably no small coincidence that the party was originally at Vinyl, even though I never went there.
