We're going to be having a semi-formal wedding in the evening with drinks, dinner, and dancing. My reception venue offers kegs (at $300 for about 200 servings) or bottle of domestic beer for $3 a bottle. Obviously, the keg is cheaper. And the catering coordinator said many brides choose the keg and she doesn't see any issue with it (which I originally thought was kind of strange, since it meant they would be getting less money). My mother, however, thinks this is totally tacky, especially for the formality of the event. What does everyone else think?
