"We love Four Barrel not just for excellent espressos, almond milk lattes, and Americanos, but for their very genuine commitment to community, both local and global. Putting their massive warehouse space to good use, they host regular workshops (pickling classes with Bar Tartine's Cortney Burns sounds especially fun) and make it a point to only source beans from small family farmers all over the world. In a pretty brilliant move, the café doesn't have wifi, so people are forced to converse face-to-face rather than hide behind laptops. There's also a location in Alamo Square and the Mission."
