Ladies: How do you react to a guy inviting you to hang out in a strip club?

About 6 months ago I was with 4 of my female friends and we went to a chip 'n dales to have a girls night out. Well we had a good time but half way through the night these two guys who my frined Cindy invited cam in and hung out with them. I thoguht they were gay but to my surprise they were both straight and just hanging out. The fact that guy strippers were dancing on stage did not bother them and I kind of felt a little nervouse but in like an ok cool way. We were there for like 2 more hours until we left and Cindy left with on of the guys and the other guy just went home but thanks us for a fun time. Yesterday we were all invited to go out with them again this Saturday but they are going to a girl strip club. I really don't know how to feel about it since they were very cool at the chip n dales. Also I am not sure if the environment will be the same. any advise cause I am thinking of going with them?
