San Franciscans seem to crave caffeine as much as they do burritos and cocktails. Some of the city's dwellers are of the grab 'n go persuasion, caffeinating on the way into work in the Financial District. Others fall into the MacBook-loving yoga teacher/"freelancer" variety, who spend hours plugged in and sipping away on soy lattes.

That said, there's always room for more beans and brew, so it's exciting news that three beloved coffee shops are opening new locations in the city. Come find out which ones they are!
