A: First, let's tackle the main problem. Serving a person a slice of cake when she's ready to sit down to dinner is guaranteed to disappoint. To remedy that, move up the ceremony to 4:00 p.m. (or after 9:00 p.m.), when it's fine to only offer cake and champagne. Include an enclosure with your invitation that reads: "Champagne and cake to follow at Bayside Country Club" so that guests know what to expect. If you have your heart set on a 6:00 p.m. ceremony, serve a simple—but complete—meal.
