Yes we have one, it gets used for birthday parties every Saturday (usually at least 3) and sunday too. the rest of the week it generally sits empty, but we are working on something now for businesses to change that.
Our shas 4 really, really old video games in it that are on free play. We only charge $10 per 1/2 hour to basically just cover the clean-up and supplies (paper plates, forks etc...) Sometimes I wish ours was a little different. It would be good if we could divide ours into two with a sliding wall or something so we could use it more on the weekends.
