Calculating how much to serve at your reception can always be a tricky task. You don’t want to overpay and you don’t want to run out. Here is a useful graph to help you get started. Also, keep in mind the preferences of your guests. Have a lot of beer drinkers? Cut back on the hard liquor and supplement it with beer. If you know you have a heavy drinking family consider adding an extra case of wine. Do note that most locations will allow you to go over what you ordered but they may charge an additional fee.
