A brunch buffet is ideal for any size group and most occasions. It's a perfect excuse to experiment with some very imaginative menus, wines and themes. The brunch provides a flexible format for busy holiday seasons when many parties are being given in the evening. Remember to state the beginning and ending times for the brunch clearly, since a brunch can easily extend through the day. Offer a selection of foods and drink appropriate for both breakfast and lunch. Lighter wines, champagnes and fruity mixed drinks (Bloody Marys, screwdrivers, or mimosas) are good choices for brunch menus. Brunches are casual and can begin as early as 10:00 A.M. and extend as late as 5:00 P.M. This photo, reproduced on a menu cover, set the theme for an "English Hunt Breakfast."
