Servings are calculated at 4oz per serving. It is important to remember when calculating the amounts to order the mixture of adults to children, whether your group contains big eaters. It is also important to remember if food is a main part of the get together or if it is just an amenity that you are offering. Such as the difference between a holiday dinner or a buffet for a holiday party where all guests would be expected to go through the buffet line. Self serve buffets also tend to have larger portions than if an event is using catering staff to serve.
The more options available, the smaller the serving sizes will tend to be, particularly with side dishes.
Our staff can help you determine the appropriate amount to order of each product to make sure that you have enough to feed your guests without having a lot of unused food left over at the end.
