After dinner we have the option to pay by the drink or continue with the unlimited per hour rate. My mom and I are trying to figure out whats the most budget friendly but also continue the open bar all night. We have a feeling the "older guests" will take off after dinner and people may slow down on the alcohol consumption. The prices at our venue are around $5-6 for beer/wine and $7-8 for hard alcohol per drink. Should we do by the drink after dinner is over? Any suggestions would be great!!
