Highlighted by Anthony Bourdain on “Layover: Miami,” the aromas of fresh-brewed coffee and Cuban food permeate from this small corner restaurant on 6th and Washington. Locals know to head there for this masterpiece, voted Best Cuban sandwich by Miami New Times in 2006. The friendly staff layers juicy ham, succulent roast pork, Swiss cheese, a slathering of pickles and mustard onto a sliced, buttered hunk of moist Cuban bread. The secret to this great sandwich lies in its grilling. This beauty is popped into the traditional la plancha until the ingredients meld and the exterior achieves the desired crunch. Buttery, gooey, crisp, and, of course, diagonally sliced, it compares to nothing else.
