Catering Question?

Hi,

I have a catering question. We are having 90 people for Ava's Christening. i need to order 9 full trays of food. How many trays should I get of each, a pasta, chicken, beef etc? I was going to get veal but I don't know if I should waste a whole tray of food for veal becuase not everyone likes it.

Can someone please help me with this! Thanks!
Denise
