L.C.
Showcase does movie parties I think. Or maybe a movie under the stars - get a new DVD - use a laptop and a projector - and watch a movie outside with smores and pop corn :) Parents can come too - like a drive in theatre.
Dave and Busters does parties but they might be a bit pricy.
I have heard that some karate studios do parties also - some gyms do the same thing.
Good luck!
