Do they have any food on site to buy? Pizza, etc. If so, what are the prices?

Yes. Pizza is $3 per slice, there are chips for $1.25 (I believe), and they have an ICEE machine on-site for $2 and up.

Have pizza supplies by vendor. Can have anything you like delivered, bring from home, etc.

No food.. but you are allowed to bring your own, if your hosting a party

Yes but not much. I've had pizza delivered there a few weeks ago
