We are going to have an open bar at our reception. I'm trying to decide if we need to have wine "served" with dinner or just have guests continue to go up to the bar if they want a glass of wine with their meal. I am thinking that if we have the served wine, a lot of alcohol might be wasted, since people will either abandon whatever they were drinking before, or just let the waiter pour the wine and not drink it. On the other hand, its a nice touch to have a waiter come to you and ask "red or white?" Any thoughts on money-saving or etiquette? Thanks!
