Without knowing who he was, my wife chose the "Peter North" model. It was a good choice, and led us to many honest talks about her desires and fantasies - ones that she would act on.
That's what I observed too. It's scary in a way as the horny and pushy mob of guys forms up right away and you have little control - there's guys in the group who are not guys you or your wife would choose to associate with and they are right in there with the pack. Etiquette is non-existent in a testosterone driven mob. I'd suggest you go to the place a couple of times before you commit - go once alone and just observe and take your wife with you once, - stay back and just observe. Act like you are shopping the toys with her. Go on a Friday or Saturday night - you need to see the place at its worst. After all, it's your wife in play here. There's better paths to forbidden pleasures these days.....paths that aren't fraught with risk. Or at least not as much risk.
