I went to one in Prague (not one of the one's that is basically a brothel with the strippers advertising themselves on poles, just a regular strip club). It was okay, I guess. I'm not really sure what the point is if there's no promise of release at the end of it.
You should go to one of those then. There's tons of them even in The Bad Place.
BTW did you ever go to any Czech grindcore or powerviolence shows? There's a huge scene for that stuff there now.
Those are basically everywhere in the center of the city and more common than regular strip clubs, though they generally have covers if I remember correctly. Also I wasn't looking to spend $200 on a prostitute.
As to your other question, no. No, I would never go to one of those.
