Bullfighting bars have been around in Madrid forever. Some have lasted for decades. Others have closed down. The Criollo and Callejon, for example, have disappeared, but others have come up to replace them.
The Malacatin on Calle Ruda 5 in the heart of Madrid has been around for years.
They offer not only food and especially an outstanding wine list, but have murals on the walls with bulflighting themes and other materials on display related to the corrida.
They are truly worth a visit
