I'm trying to decide out what to do about our RD. I know it's terribly rude to ask guests to pay for anything themselves at an event that is supposed to be hosted, and I'm trying to avoid that. Due to budget constraints we're having a dry RD (because we will NOT have a cash bar) at a restaurant near our venue. At FILs' request we are doing a nice sit-down dinner, but would love to have some time afterward to just mingle with guests, and I know some of our guests will want to drink.
Since the restaurant is right down the street from our favorite beer bar, I was thinking of spreading the word that we'll be heading over there after dinner and that everyone is welcome to come. If we did this, would we be considered "hosting" and be expected to pick up the tab? Would it be rude to assume that guests who choose to come to the bar afterward would pay for their drinks?
