If café Cubano is fuel for your own biped power vehicle, then David's is the best and most convenient service station in town. Located just off Lincoln Road, this South Beach stalwart has been around for almost three decades. Every day of the year David's dishes up hearty Cuban fare in its dining room and adjacent counter, as well as keeps thousands of hearty partygoers going by dispensing café Cubano in little plastic cups from a window on Meridian Avenue. David's café Cubano has just the right combination of firepower and lusciousness; it tastes like caffeinated candy and jumpstarts your nervous system like a jolt of electricity. Plus David's is open 24 hours, so there is no excuse for burrowing your face in the pillow until the sun comes up. Or even then, for that matter.
