It's difficult to figure how much f8inger foods people will eat when it's not a meal hour. I think 2 to 4 is an awkward time for serving food....it's neither lunch dinner nor a mid afternoon snack. Will you be serving cocktails or just tea coke and coffee?
People will eat more if there is alcohol involved....it will turn into dinner.
You automatically figure 10% shrinkage even though people asy they will attend...something comes up....so that takes you to about 78. And I am assuming there will be a minimum of teenagers and people under say 35...so older people eat less too.
Because you are having so many items, you need to allow enough of each item for everyone to to have some.
You will need about 7 1/2 pounds of meatballs, 80 to 90 ham buns and if the buns are tea size that will mean about 8 pounds of shaved ham and 7 dozen buns. You will need 10 poubnds of shrimp....my experience tells me people eat lots of shrimp! and I would figure 8 to 10 pounds of chicken wings.
You will need 4 pounds of cheese....but if you are having several different varieties I would figure 2 pounds of each kind of cheese.
Veggie tray, figure 1/4 cup of cut up veggies per person, so you will need 20 cups of cut up veggies....more carrots, celery and cauliflower than broccoli or pepper strips, and about 3 to 4 cups of veggie dip.
For the fruit you will need twice the amount as you will need veggies.
You will have lots of leftovers.... but you have to have one small serving of each item for everyone who comes....to cut down on the amount of food left....eliminate some of the items you are offering.

As always, Linda C has good information. You may also wish to check out Ellen's Kitchen, which has a helpful quantity chart.

We're having a 50th anniversary luncheon party for my parents at a restaurant. The menu consists of (that I know of) Veggies and dip, cheese and crackers, salad, salmon and beef, apple cobbler and anniversary cake.

I am then having 24 adults and 10 children back to my house for the evening. Not sure what to serve. I don't want to be cooking since I will not have enough time to do much once we get back from the party and before everyone arrives. I was thinking sandwich wraps, veggies and fruit, hummus and salsa and chips. Cookies and such. What else should I serve? Should I serve veggies and cheese tray if we are having it for lunch?

Thanks for your help! By the way, its this coming Sat!
