Totally unrefurbished, La Venencia is gloriously shabby, with old, peeling sherry posters, barrels behind the bar and walls burnished gold by decades of tobacco smoke. It serves only sherry (locals will order a crisp, dry 'fino' or 'manzanilla', leaving the sweet stuff to the occasional tourist who stumbles in), along with manchego cheese, 'cecina' (air-dried beef) and chorizo by way of tapas. You’ll invariably be served some excellent olives with the first round. Orders are still chalked up on the bar, and an enamel sign asks customers not to spit on the floor or take photos. No tips accepted.
