Drinking is for after work, somewhere other than work.
The liability issues alone make "listing" drinking alcohol at work during or after office hours as a "job perk" even more moronic.
But do feel free to list right here on HN the startups who proudly list beer drinking during office hours on office premises as a "perk".
There are many of us who do business in the tech world who will consider that a public service announcement of organizations to avoid doing business with.

As well as bunch of other names I've never heard of (Forio, Reesio, thredUP, UberConference, FiveStars, PagerDuty)
(Not that it stops Google employees from feeling deeply entitled to have free beer every week...)
You're talking about this as if the idea was to get everyone drunk at work. Spoilers: it's not.
Sure, "I do not want to drink at the workplace, I don't mix work and fun". It's sad you feel that way but you can't deny the team-building aspects.
The good thing about "drinking at work" is that it doesn't exclude anyone. You don't have to think "we're going to bar X, how will I get there? then come back home?". You're already there so staying up 20 minutes to an hour more just to relax and do something different with your colleagues is not too much of a hassle[1] :)
