what food to serve at childrens roller skating party ?

[lilyloo]

Dds are 7 and 10 next week. We have hired a hall and they are having a roller skating party.
I was just planning on leaving food on the table for them to help themselves to.
It's 2-4 so not a meal time.
What type of things would you suggest ?

I'd do snacky foods like;

Crisps
Fairy cakes
Cocktail sausages
Sausage rolls

Thanks I am thinking the same rather than sandwiches etc
