Street: Calle Cava Baja, 30. Madrid
A lot of wine, highly varied regions and attributes. With quality as criteria and continuous rotation. One of the best to find curiosities. The food is also excellent.
Bad points: the price of the cup goes to the normal market price but the size is smaller (wine tasting type). The Tapa, like the wine, good quality but do not expect much entertainment with it. And full, full, full of people always.
