If we were to go with a dessert bar, do we have to have enough of each item to serve each guest? So, 100 chocolate chip cookies, 100 whoopie pies, enough pie for 100 people...? Or as long as everyone has something dessert-like? If it's the latter, how would you break down the amounts--maybe 40-50 of each item? Or is that too many? I love the idea, but I want to make it happen AND be mindful of etiquette!
