I'll be going to Spain by myself for two weeks in November. I'll be landing in Madrid and then going to Barcelona, Bilbao, Grenada and Cordoba. I welcome any suggestions of where to eat (I'm looking for both cheap and tasty and one or two splurges), especially in restaurants where I won't feel uncomfortable dining alone. (Of course, if you're a tourist, I suppose it's OK to eat alone.) I also, going OT, welcome shopping recommendations in Barcelona, as I'm arriving on Monday when all the museums are closed!
