We have a very small budget ($5000 TOTAL for wedding!!) so we are thinking of having a buffet dinner. I was thinking of ordering from olive garden. My problem is that i cant figure out how much food to order for 100 people. There will be several items (lasagne, spaghetti, chicken...) how do i know how much to get? If i order each item for 100 pl then i will have alot of left overs i think. Please help!
