Yes, I have been to Rascal's.
You will be hard pressed to find anyone who volunteers to take you, based on this particular medium.
My best advice is show up. Tell them that you are new, when you walk in the door and pay your small fee. They will look after you.
Dress appropriately, or don't expect to enter.
Just be honest, honey. There are lots of people there, happy to play with newbies. If not, they will sit down and discuss the things that you should know about this kind of play.
It's exciting, but there is a lot more than meets the eye. Do your research.
Good luck!
