Located in the popular Castro Village shopping center, this Starbucks gets more foot traffic than many. Even mid-afternoon, a half dozen people can be seen sipping the popular Frappucchinos or lattes under the chain's signature green umbrellas on the patio out front. While always a reliable place to secure one's caffeination, this Starbucks location is also a great place to peoplewatch, to see and be seen. It's open late, too.
