About ~8 years ago, in one of my previous jobs, we would start around 4PM almost every other Friday in the office and go till about midnight or after. It really depends on the company, environment, and people. We even had non-drinkers tag along as well. Probably not the healthiest environment to be in, but it was fun while it lasted.

I can't comment much about nowadays, as I haven't worked from an office since 2020. But from what I've heard, you're correct, those times are somewhat behind us in most of the companies.
