What aspect do you always put the biggest stake of your budget at for your kid’s party?

For me, when it comes to parties in general, I'd spend the most on food and drinks. What's a great party without yummy stuff to enjoy. Moreover, living in a country that's pretty much food crazy, the first things your guests will talk about during and after the party will be the food. With kids parties especially, you'll probably spending quite a bit on cute customised cakes and treats :)
