My son is getting married in a couple of months and I trying to figure out what it's going to cost me...the groom's father. I know that I am responsible for the rehearsal dinner and that's not much of a problem to figure the cost of but the tough question is the bar. He's told me he only wants beer and wine but I have no idea what that's going to cost. There will be about 100-125 people there and probably half of them won't drink much at all. The other half will probably make up for them. So here's what I'd like to know...How much red/white wine and how much beer. He wants a couple of types of beer but I don't have any idea what that's worth. I'm also guessing that a half barrel (served) is a cost whether it's consumed or not is still a charge as is the wine. Soda is probably something else I should consider. BTW, I don't have any intentions of throwing a beer party even though his 25-30-year old buddies would like me to. I want to be generous but not to the point that we'll have problems with drunks. Can anyone help me out on this?
