We are having DD's 3rd birthday at an indoor playground from 10am to noon. I am not too sure what to do about food. Should i have food out buffet style, and parents can feed their kids when they please? Or should eating time be at a specific time? We were going to do cake at 11:30am - hope that's not too early! Also, with the party being so early, any suggestions for what would be good to serve - brunch type items or could i get away with ordering pizzas?
