The Best Restaurant in Belém, Lisbon

This bakery specializes in pastéis de nata: delicious warm custard tarts sprinkled with cinnamon and powdered sugar. Although these sweet treats are ubiquitous in Portugal, the version here is celebrated as the original, made here since 1837 using a secret recipe from the nearby Mosteiro dos Jerónimos. They're so good that lines snake out of the door of this traditional blue-and-white-tiled establishment. Luckily the lines move quickly, especially if you are just getting take-out.
