Hello, it's the age old question of whether to pay for open bar or to do consumption instead.  The cost of open bar for our venue comes out to about 7 drinks / person for the 4 hour reception.  I've tried to do research but I mostly only find estimates and guesses from brides who are still planning their wedding.  For those of you who already had your wedding, do you know what was the average number of drinks your guests had?

Thanks so much!!
