I like trance/techno clubs but there are not many around here in Boston. The only one that i've been to is Avalon which was pretty nice.
www.avalonboston.com There are also avalon's in miami and LA I think..
All the clubs in Boston are 21+ now (new city law as of 6 months ago) so I have to wait another year to start going again.
I have also been to a few in NYC, but I haven't found any good ones there yet. NYC has tons of clubs and I don't know anyone from that area so it's hard to find the good ones. I heard Crobar is the best but that's 21+ as well.
