Meet with your caterer at least six weeks before your wedding. You should already know your budget, the total number of guests, the time of your event, the food selection and service style and the type of beverages you would like to serve.
Review the menu with your caterer and clarify if they are willing to customize the menu to reflect your tasste and your guests. Also note the type of events they have done in the past and how many servers will be assigned to your event.
(the general rule: one server per twenty people)
When comparing caterers, make sure you are comparing equal menus. Remember the right caterer will bring professionalism to your "Special day."
