Coffee continues to be the most efficient fuel for the human body's complex system of fuel injectors, auxiliary hearts, and flux capacitors. Fill up your flesh tank with today's Groupon: for $6, you get $12 worth of café fare at Zucchero Cappuccino Bar & Panini Grill.

The European-style Zucchero Cappuccino Bar & Panini Grill serves up a bevy of Italianate coffee-shop items, including the titular potables and edibles, in addition to gelato and homemade desserts. Cosmopolitan customers can quaff coffee drinks, such as frothy cappuccinos and hyperactive espressos ($1.50–$4.50), decocted to deliver a jolt of energy able awaken the bleary-eyed or reanimate the cryogenically frozen. Meanwhile, Zucchero's generously portioned paninis, grilled and pressed to a state of wrinkle-free delectability ($6–$8.50), vie with soft, rich gelatos ($3–$4) for a chance to satisfy caffeine-free culinary cravings. A pair of plasma-screen TVs offers visual diversion, or visitors can play a round of Italy's favourite national pastime, Greco-Roman foosball.
