Are restaurants okay, or are you specifically avoiding alcohol? St Claire Social in Friendship has a fun trivia on Wednesdays, and their table spacing and good menu are definitely more restaurant than bar. But of course they have a bar as well and serve alcohol. If you want somewhere to take along a late teen or 20yo that can't get into a bar, it's a good choice.
I like the trivia itself because it's more general knowledge and not just pop culture for 20-somethings. The host is fun, though may not be your thing if you're prudish.
