DD's rehearsal dinner was upstairs at this place:

And it was fantastic!

We are going to Charleston in June to celebrate my sister's 50th. I would like to book something semi-private for a little party with family. There will only be 10 adults and 6 kids (varying ages). I'm imagining a back room of a restaurant or a party room at a cool hotel. Budget isn't really an issue, but I don't want to go too fancy, especially since some kids are little. Does anybody have any suggestions?
