I generally pick out of the way venues, and adjust times as well, for such eves. Places that do more than enough business to be open, but not so much I have to concern myself with elbow rubbing or either loud or nonsensical folks.

Jamil's
OKCCafe (or whatever it goes by) in the Crown Plaza, NW Xpress & May
Gopuram the semi-private areas, not the main room
The Mantle in BT

I'm sure there are others I just haven't made it to thus far
