FH and I aren't sure which one we're doing, but we know we'll either have a cash bar or no bar. We will be providing a champagne toast to all guests and the debate of is a cash bar/no bar tacky is another issue
Anyway, I want to inform guests before the wedding that there will not be an open bar because I don't want them unprepared when them come to the reception, but how and where should I put this? Does it belong on the invitation? Or what?
