Personally I thought the food was "just ok" anyhow. Not bad. But not the reason I'd plan this event. In your case, I'd eat light before the event. Then eat the available green beans, carrots and potatoes from the meals (leave the meat) then clean up on desserts. But you'll find you'll be having so much fun dancing and meeting villains that it won't matter!! Just don't place too much emphasis on the meal (as most of it is indeed non-vegetarian) and you'll have an amazing night. I drank 2 IPA's (beers), my wife had water and my daughter had a soft drink. So drinks were far from a deciding factor for us, as well. In fact we'd have had just as much fun without alcohol altogether.
