Churros, a typical Spanish breakfast consisting of fried dough served with a thick hot chocolate, is also a big (and very messy) hit with children and sweet-toothed adults alike. If you would like to try them (or melindros, a local variant), there are several options dotted around Barcelona's old town. Granja Viader is a family-run café that has served the good stuff to punters including Pablo Picasso himself since 1870, and incorporates a small deli counter for you to pick up treats for later. Another good option is Cafè de l'Òpera, a haven of proper food and tranquility amid the noise and bad paella of Las Ramblas. Kids will love the churros and pretty cakes; grownups will love the neoclassical decor and similarly chic drinks list.
