We are having an "after party" in our hotel bar which will last from 12:30-2. We are serving food, but the bar will be cash at this point (we are having an open bar at the reception). I want to include this on one of the cards in our invitation, how would you suggest wording this? I just want everyone to know so they take advantage of this, but also feel weird using the term cash bar as people might think my whole wedding is a cash bar,
