While not certain, sitting in the bar during my visits I believe I have seen several sets of parents with their adult kids come in for a tour of the place. Usually it appears they are with one of their kids and their significant other. The only time I recall seeing a member of “the group” party was a few years ago, a Dad had brought his Son in for his 21st birthday to lose his V-card. I have also seen several groups of guys come in and sometimes they just play pool, sometimes a couple of them will party. It’s really an anything goes place where you won’t be judged. Good luck & enjoy!
