Social games for ~30 people

[Xdaamno]

I'm attending a wedding later this year. After the wedding proper concludes, there'll be about 30 people hanging out with snacks.

Does anyone know social games that work well for that number of people?

The newlyweds will be nerd-adjacent enough such that off-the-wall suggestions are not immediately disqualified... Though of course, you'd like everyone to have fun, ideally.
