If you're under 35.5 years of age, check out HipTix.com for awesome pricing and the occasional free post-production party with comped wines and bites. I've literally been using HipTix since I was 19.
The food was pretty typical theater-faire and pricing. $4 for a bag of M&Ms, $6 for a small bag of popcorn, etc. I also thought it was strange how the actors broke character to ask for donations. :)
