This was the real authentic experience, there was nothing fancy about this place, it was close quarters, had a very intimate feel, amazing acoustics (the ceiling was many stories above us), only the guitarist used a microphone, the walls were highly decorated, and the performers did everything from performing to taking tickets at the door to seating us to serving food and drinks.
Like I said, it was super authentic emphasizing the core aspects of Flamenco: percussion (hands and feet), voice (no microphones), guitar, and dance. The guitarist was better than any I have seen in person, Flamenco guitar has such a fast pace it was incredible to watch his fingers. The dancer, who was also one of the two vocalists, was the wife of the guitarist and had so much passion in her movements.
Beyond the performance and atmosphere the service was excellent as well. The show probably started about one hour late but that was partly due to the performers serving us our food and drinks and just geting back from being on tour. For 30 € we both got tickets to the show, one drink each and a meat and cheese plate to share. As a drink we got a specialty sangria that they made, it was only ok but the meat and cheese were perfect to munch on and we weren't even expecting it!
