I'll say, haven't been in a while, but my brother lived in SF and then Palo Alto for a bit during and after law school, so 2009-14 we'll say, and I had a blast every time I went to visit. I haven't been back since, and obviously people say the city has changed a bit, but back then it was such a different lifestyle from the East Coast.
I always go back to this story, at that time Dunkin Donuts's catchphrase or whatever, at least in the NEC, was America Runs on Dunkin, but when I went out west they would say America's Favorite Coffee, and I always found it a pretty apropos juxtaposition of the coastal mentalities. In NY/NJ, we were all about work. Everyone works, you go out after work in your fuckin suits, you talked about work. It was a culture, and it ran on coffee (sometimes Dunkin). But out west, people seemed to be more interested in taking in life, the sights, the food, and yes, the fucking coffee.
And the catchphrase for the middle of America was "drink it or don't, nobody cares about you".
