hmmm....that's weird that the guys were'nt allowed into the bar period. I live in B.C. and maybe things are different, but usually when a bar has a ladies' night here, it just reserves a section for the ladies' entertainment, and has another section for the guys until 10 pm or something.
I don't go to ladies nights much or at all actually, but I have happened upon a club where it was going on, and they were showing mud wrestling on the big screen for the guys, while the male dancers did there thing.
Never really thought too much about it being sexist! I mean there are 100's of strip bars your buddies could go to if they want I'm sure. I understand that's not the point...but really, I don't see what the big deal is!
