Patéis de Nata at the famous café, Pastéis de Belém
In Lisbon, one thing that cannot be missed, for historic and gastronomic reasons, is the Pastéis de Belém Café, which makes the most famous pastéis de nata (cream custard tarts) in the world. Since 1837 this establishment has been offering this delicacy; the recipe is still the same since the café opened, meaning it is one of the best-kept secrets of Portuguese cuisine.
