Casa Mingo is a really neat bar located on the Paseo de la Florida. It offers its own cider and I'd recommend you order some pollo asado with it. It's actually next to San Antonio de la Florida Church where you will find frescoes painted by Goya. Notice the exact copy of the church next to it. (One of my favorite restaurants in the WORLD!)
Casa Macaya, Barcelona, Spain. Declared a Cultural Asset of National Interest, the Macaya house was finished in 1901. The architect, Josep Puig i Cadafalch, revived the grandiose of the Gothic style with his design of the facade. Arches & columns are intricately carved & decorated by ironwork next to white stucco walls with elaborately engraved designs.
