My extremely low maintenance best friend is engaged

I'm so excited for her and she is too, but she wants a very intimate wedding. Her only request is to have a dance with her dad. All of our girlfriends have had country club or city weddings and she isn't much into wedding planning so is a bit lost on where to start. I know she doesn't what what I had or what our other girlfriends have had, but I want to help her out. Any suggestions for spaces in the Drexel Hill area that would be for under 100 people, budget friendly, and low-key? I'm thinking a restaurant with a nice room and space for a dance floor, maybe an afternoon thing at a country club. She will have an extremely private ceremony and then just wants to party afterwards

Thanks!
