I want to start out by saying I've always been against cash bars. They just seem out of place at a wedding.
Anyway, from the beginning, we knew we would be serving beer and wine. My mother and step-father are paying for alcohol and that's what she wanted to offer. Our wedding isn't that big. I've personally spoken to everyone on my side and asked them how they felt about there only being beer and wine. Everyone is okay (again we're talking about my side). When I initially approached FI, he said that most of his family doesn't drink. Beer and wine would be fine.
So, the venue said that they can only put out beer and wine or they could offer cash bar for liquor. Cash bars aren't really common in my area, at least not for weddings. Now, my fiance and my step-father think that we should do the rest of the bar as cash. I don't want to. The venue is attached to a restaurant. If they really want a drink, there is a bar down the hall. I think that should be enough. Having things for sale at my wedding makes me uncomfortable. Opinions?
Edit: I know that cash bar comes up a lot on E. I'm curious as to how you would feel as a guest if you encountered this. I'm very biased because I'm not a big fan of liquor. When I go t a bar I usually stick to wine.
