Who says you even have to have a real bar? At an informal reception, fill metal tubs with ice and chill bottles of beer and wine and let guests can serve themselves. A waiter can pass champagne for toasting. How about serving just beer and wine and maybe one signature drink -- something that has special meaning for the couple? Did you meet over apple martinis at the neighborhood watering hole? You can also reflect your heritage in your choice of drinks. Is the family from Tennessee? Jack Daniel's can be your choice. Getting married at the beach? A fruity cocktail is in order. Guests will always remember those drinks and how much fun they were. They won't realize that you saved time and money at the liquor store.
