This traditional tavern opened in 1909. El Anciano Rey continues to serve up wine and tapas in the same professional manner as its opening day.
Indeed, the bartender here, Tanis, is famous for having worked over 45 years without missing a day. That alone should recommend the vino dulce, sweet wine (often referred to by locals as vino El anciano), paired with a round biscuit, galleta redonda, which is a house specialty.
This particular mix of wine and wafer is especially potent as this bar stands across the street from the Almudena Cathedral and receives a good share of patrons coming from mass.
