What is an arcade and theatre in an adult superstore?

I have been in a few adult stores and there are always some with arcades and theatres in them, and some even had a gym. What do you do in those? What is all of that? Does anyone know?? Thanks!

I have never been in one but the arcade I am sure has sex games. The theatre shows porn, and I haven’t even heard of the first two in an adult store. I guess you could work out in the gym.
