If you want a quick tapas session rather than a full sit-down meal, follow the oscenses (people of Huesca) down to the ebullient bar strip of Calle Padre Huesca. One of the best options here is the congenial Da Vinci, where tasty morsels are ranged along the bar and there's a menu of bigger raciones.
It’s a popular spot but should the tables fill up, there’s plenty of room at the bar.
