Definitive menu for a party of 20 nine year olds

[MumsMan]

DS1 is leaving his school to join the local preparatory. We have invited his class at home for a final get together. What should I do for the food? All I can think about is chicken nuggets and fries plus Fruit Shoots in different flavours. Give us some ideas here, pleeeeese! The science tricks man is also coming but his show wouldn't last longer than an hour although he'll walk away with my right arm and left leg. I don't want them to be bored so its got to be loads of food, music and parcel parcel. Please help us with this menu thingy. Thanks in advance.

Don't give them shite, they will be hyper.

Decent crisps, fruit (really!), biscuits but no hideous colours, um... decent sausages? I hate parties (bah, humbug!)

Tortilla chips and dips.

9 year old boys??

burgers, fries and hot dogs

home made milk shakes for drinks

job done

Pizza goes down well with children that age IMO. Take away or Frozen OR if you are up for it, home made (using ready made bases or even turkish flat bread makes an excellent pizza base)
I wouldn't do nuggets or any kind of coloured drink

well, maybe cordial ...

Thanks for all the replies. I am thinking about Pizzas as well. Just a phone call and you are sorted! Can do some nuggets as a side dish. The thought of frying the stuff and then doing the greasy dishes makes me shudder. Please keep the ideas coming.

My first idea was pizza as well but since that has already been suggested how about pitta breads that they can fill themselves.

put out pitta breads
mince sauce
small meatballs
cucumbers
lettuce
mini sausages
grated carrot
tomatoes
mini sweetcorn
sweetcorn
peas
ham
cheese

You could also put out some melon cut into squares.
Mini apples and pears.

AND of course a big cake
