Bars are notable for staying open late, but I’m not really familiar with alternatives that might operate similarly. I think many cafés (at least around my area) tend to close a few hours earlier by comparison, which would be my go-to for an alternative otherwise, so what other options are there?
Pool halls. I think some bowling venues. Less common, we have a cafe full of hundreds (maybe thousands) of board and card games. They’re only open until 11pm, but that’s still a place to socialize and meet up with people at night.
