Meet at Mint Plaza bike racks outside Blue Bottle Cafe (66 Mint St.); Take a tour of six of the City's finest espresso joints according to CoffeeRatings.com. Bring your own mug if you prefer to pace yourself and share an order of drip coffee with new friends. The pace will be leisurely, but we understand if you're a little jacked up after six shots. Heavy rain cancels. Preview the course, and contact Frank if you have any questions.
