You can customize the menus they give you, so
1) I took out the fish and put in a pasta dish ( my family isn't that big on fish but LOVE pasta, so it made sense) so we had a chicken and a pork choice with pasta and grilled vegetables.
2) I requested that they change one of the salads on the menu to Italian Wedding soup.
3)I also took out the dessert since we were having cake and then the dessert party later.
If I remember correctly, we saved about $12 a head.
I just emailed my planner with my requests and she would talk to the chef/kitchen about it and come back with a per person estimate.
