Wedding/Event Afterparty locations?

Hi!

Having my wedding in the area in August, I am looking at potential "after party" places.

Just somewhere a group of 5-20 people could go, and continue celebrating that isn't someone's hotel room. (A hotel bar would be fine, but not sure how late they stay open).

Somewhere that is open late on a Saturday night, doesn't have a cover and anyone could possibly dance. Preference to somewhere that's not owerwhelmingly loud, so people can still converse and serves food to possibly get a snack.

Nothing is or will be set in stone, I'm just looking for ideas.
