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?
One of my absolute favourites is an arcade bar near me that stays open late. I don’t usually drink there but I’ll go and hang out with mates, get some chips and play some retro arcade. Super chill vibe and people there all seem way more chill than most pubs or bars I’ve been to!
