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?
Whataburger, Winco Foods, insomnia cookies, Denny’s, and other diners come to mind. Since covid, hardly anything is open late anymore.
You might be able to find some other places local to you that we won’t know aboht, if you satay up late and use the “open now” option on Google maps.
