The short answer is yes. The club absolutely hosts comics who have material that is considered "clean". The best way in my opinion to make sure the act will be appropriate for you would be to look at the callander and go to a show of someone you're familiar with. Helium is a great place.
Check out the comedians coming up. That's the best way to get what you're looking for.
I'm sure they do but I've never seen it. Call the club for derails.
