We ordered a fritter for four people, each paying €9. It's ample, and the desserts were also very good, especially the puff pastry with cream and chocolate. I have to say that the migas (breadcrumbs) are very simple, as they don't contain chorizo, peppers, or anything else—just breadcrumbs, but they were good. The ham croquettes were also very good.
Almost everything is gluten-free, so that's a great point in their favor. Plus, you don't need a reservation, so there's plenty of room.
