When it's too late for a full meal but necessary to refuel for the last leg of your long night's journey into the wee hours, the take-out window at La Carreta is the perfect pit stop. For a dollar and a half you can order a steaming cortadito (sugary espresso coffee softened with a big splash of hot milk; also available without sugar) and a warm and flaky pastel de guayaba (guava pastry). If you arrive after the window closes at 2:00 a.m., you can still order at the counter inside the main restaurant. This branch of the local chain happens to be the only one open 24 hours.
