Cafes are an integral part of Parisian life, and you can linger as long as you like over your espresso (sometimes longer, depending on the waiter’s whim). The choice is virtually limitless. Pose outside the ritzy Café de la Paix at Opéra, or ponder the meaning of life within the hallowed walls of les Deux Magots? Then again, why not watch the world go by from the comfort of your local zinc bar? You’ll be surprised how quickly you become one of the regulars.
