Thanks a lot for that I will let you know how it goes. A bit disappointing about The Guggenheim as "The Doris" wants to do a day in the Gallery there and the reviews of the restaurant that I read have been good; oh well!
I will be in Bilbao on Thursday, then San Sebastian for three nights followed by a night in Zaragoza on my way home to Javea. Think I have Zaragoza sorted out, any recommendations for tapas in the other two?
