The one in Central Madrid? Do you mean the one in the Puerta del Sol? Have you tried their website @
http://www.elcorteingles.es ? I'm sure they have a store locator there.
El Corte Ingles
Calle de Preciados, 3
Madrid, Spain
Phone: 91-418-8800
Also, please remember to put the CITY NAME in the SUBJECT line (I've fixed yours) of all new threads as this is an ALL SPAIN Message Board. Thanks!
Saludos, MadridMan
