Blue Bottle Coffee
Hidden away on a side street by Patricia's Green is this modest kiosk where the organic beans are ground for each cup and the espresso is automatically ristretto—a short shot. While Blue Bottle is now a global juggernaut (the blue, boutique equivalent of the green mermaid chain, as locals like to say), Linden Street was the first brick-and-mortar shop, and it's still a San Francisco coffee lover's favorite.
