There used to be one called Pancho Villa out in Almeda de Osuna (i.e., 28042 Postal Code). I believe it was owned / operated by a retired USAF Sergeant.

Eddie, when i used to lived in Madrid back in the 70's I knew a USAF sargeant that when the Torrejon de Ardoz US Base was closed decided to stay in Madrid; maybe he open this Pancho Villa place. DO you his name? He used to umpire the baseball league at La Elipa park, and the USAF had a team of kids of service personnel that played against us in the Madrid league. I was with the Real Madrid (yes they also sponsored a baseball team back then)::)
thanks
