While Los Toreros is a place with the best tapas, Granja M Viader, Barcelona's oldest café, is one where you can taste the best hot chocolate in the city which, as you know, was brought to Spain from South America for the first time. The menu of the café offers only desserts, and on the counters, you can find dessert cheese, biscuits and famous Spanish cacao Cacaolat, the gem of the Spanish chocolate production.
