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?
I used to belong to D&D groups that were open at a local comic store till like 4am.
We’d rent the space from the store at a good price, have pre-made characters for those that wanted to jump in.
If you don’t have something like that local, I can imagine it wouldn’t be too hard to start
