My daughter is getting married this Valentine's Day, and we saved a lot of money by doing it buffet style. This cuts down on the labor for the caterer, and makes the excellent food more affordable. She chose a salad, rolls, 3 pastas, 2 meats, and appetizers of veggies and cheese, all for $13.00 per plate.

It really depends on what you want to serve and how many people you are serving. Many caterers charge per person and menu. To cut cost you could do the appetizers and desserts, use caterers for main course selections.
