If you are not Spanish, stay out. As our group looked particularly 'foreign' ( read four blonds from the North, 2 girls with elderly parents) they treated is with utter disdain, not a single smile, proactively indifferent to us ordering. When we asked if by any chance they had wifi, we got an aggressive 'it is not my obligation to have it'. We had quite some loud discussion as we did not want to pay for such a horrible service, we wrote an official claim while the owner was outwardly shouting at us. We paid and the owners did not even try to apologize! The food was no more than average, but the roughness of service was overwhelming. Stay away unless you look 'local', do not let this place spoil your Madrid experience! Update: I left a negative review on their FB page, and instead of apologising they blocked it, threatening me to block my account - this is just absurd, these guys do not know how to work:) read more
