Jack's Library
Madrid is rather new to the speakeasy scene, which makes Jack’s Library even more fun. The secret bar is located behind the front of a flower shop, where you’ll have to ring a doorbell, then enter a code (that’s provided when you make a reservation) for a hidden door to swing open to a dimly-lit, 16th-century British library bar.
Put your phone away (photos are prohibited) and order a simple, perfectly-prepared cocktail. Drinks are named after artists and writers, like the floral and smoky Juan Rulfo (mezcal, jasmine essence, passion fruit, fresh lime zest) or the refreshing George Orwell (gin, elderflower liquor, fresh ginger, lime juice, and ginger beer).
