Seaports not bad spot if you have one night. Not going to give you a “true Boston experience” but you have plenty of restaurants, a brewery (trillium), and I think they just opened some indoor mini golf bar down there too.

If you’re looking for another neighborhood that might give you more “Boston” vibes the south end has a ton of amazing restaurants, you could also catch some live music at the beehive or Daryl’s.

Last spot I’d suggest is fenway. There’s plenty of bars there, outdoor beer garden, and a giant food hall. 30 year olds might feel, well old, depending on where you go.
