If you're flying south from the eastern United States, chances are you'll transfer at Miami International Airport, and you'll be hungry when you do. Thank goodness, then, for La Carreta. The branch of this Cuban chain in Terminal D quiets travelers' growling stomachs with rib-sticking food: juicy roast pork with a heap of black beans and rice; rich oxtail stew; sliced steak with onions; and a Cuban sandwich so classically gooey, porky, and cheesy that it sets your air-weary soul right back on the ground.
