Los Gatos

With their reputation for staying out all night, the good people of Madrid are popularly known as 'los gatos' (the cats), and there's nowhere better than here to begin a night prowling the streets. The bar is hung with all manner of paraphernalia, from gramophones to choirboy mannequins, but what really counts is you can get a selection of tasty canapés, and a good frothy beer.
