Everything will be in the playroom. We're expecting 10 adults and 7 kids. Could you suggest how much food to order so there's enough for everyone without too much waste? I'm thinking pizza, fries, maybe some fruit (though not sure if anyone will want it), and what else should we bring? A cake is definitely a must! 🎂
