"Four Barrel, Mission District by Avocados and Coconuts. Four Barrel is an anchor of lower Valencia street and one of the first of its kind in San Francisco. With its large space, parklet and delicious single origin coffees it is a place to spend some time. Whether you prefer a cap or a black pour over you're sure to get an amazing cup. They source their beans directly from the farmers in places like Ethiopia, Honduras and Guatemala which gives farmers better wages and you better coffee. Win win!"
