So, I know a cash bar is a no-no (I agree that I hate that) but I met with a reception venue today and with their one wedding packages, the bar will provide unlimited draft beer and house wine(8 selections I think) and soda, as well as the toasting champagne or wine. That would all be free for the guests. But they do have the bar open if the guests did want to buy something else. Is this so wrong, if we are providing alcohol? I'm not sure how this would work as far as etiquette right and wrong goes.
