I moved from Seattle to San Francisco a couple years ago, asked Yelp for the best coffee and was sent to Philz.
I experienced some culture shock learning that San Francisco's top coffee shop didn't serve espresso. The idea of a coffee shop without an espresso machine had never crossed my mind. I left confused, with a scalding hot pour over, and moved back to Seattle soon afterward.
Blue Bottle and Four Barrel Coffee were both excellent.
