I can name several of my favorite coffee shops that reside in San Francisco and Four Barrel would definitely be at the top of that list. In fact, whenever I make it out to the city during the day, making a stop at Four Barrel is absolutely necessary. There is something so cool and relaxed about this environment that it makes me come back again and again. I remember it now. Dark wooden walls with rotating local art. Minimal menu. Long line. Outdoor seating area. The amount of cool people that fill this place up. It is all so wonderful. The baristas are mellow and just so damn hipster, it is amazing! Be sure to grab a latte next time you are in the Mission District. But be prepared to spend somewhere between $4 and $6 dollars. Good coffee is NOT cheap.
