Here is what I will say. Drinking certainly is not a healthy choice. However hanging out with your peers for a few hours a night in public certainly is.

Unfortunately I haven't found any place that cracks that problem in america, especially into the later hours. There isn't really a place for people to hang out and socialize without it being a boozy bar. As someone who doesn't really enjoy drinking I don't even really want to go to boardgame/chess/trivia nights at bars because I feel like I'm freeloading. ( I imagine any given bar patron is having 1-3 drinks per hour and potentially ordering some food if that is an option. I might order some food and have a soda...)

I assume part of the problem being that alcohol has the helpful side effect of greasing the wheels socially. Coffee houses that are open late are generally library like affairs, a lot of people sitting around on laptops or with books, any attempt to start a more social night is, in my experience, refused because of this.
