Went in there for 3-4 hours Wednesday night (Aug 3rd). My friends and I had a really good time. No 10s but no 4s either. Except for 1 or 2, I probably got a dance from every girl on the night shift. Hard to beat $10 "hands on" lap dances.
Between Paradise Saloon and the Outhouse, Lawrence has ruined Wichita strip joins for me ($30 sit on your hands lap dances here).
My guess from experience is no extras available in the club but as with most strip joints money will probably talk for extras outside the club.
