Our food is $34pp and I believe you pay full price for children too. We completely customized our menu, I just picked things that everyone liked and asked my planner. She then asked the GF chef's and came up with this price.
We are having:
-Key lime tarts
-Mini Tiramisu martini's
-Chocolate fudge brownies
-Cheese board with brie etc
-Coffee's with whipped cream, chocolate shavings etc
I also asked for rice crispie mickey head things and they are $62 per dozen, but I don't know if I am including those yet. Don't forget that there is a 21% service charge and 6.5% tax on all food.
For 10-12 people, even with a $34pp menu, you would only be looking at $400-$500 anyway
