Tips from locals
Third wave coffee place that originated in San Francisco. It's like the Trader Joe's of cafes. Come here for "interesting" coffee and tea (like coffee with cardamom and mint!) and to do some work on their free wifi.
Bay Area favorite - there's a drink called a mint mojito that is alcohol free, but don't worry there's plenty of caffeine.
