After the rehearsal dinner we plan to go hang out in the bar attached to the restaurant, and we would welcome anyone who is town to drop by and have a drink with us - but we don't plan on hosting the bar. Is this ok? If so, is this appropriate wording?
"In town the night before the wedding with not much to do? We will be having a drink or two at our neighbourhood restaurant, and would love to have you drop by and say hi!"
If not hosting the bar is poor etiquette I can try to work something out with the restaurant (they won't be shutting the bar down just for us, so it would require drink tickets or something to seperate our guests from the general public).
