This sounds like a travel question, but it is really a food question. Believe me, it's very much a food question.
I have two grade school kids. I want to go to Spain next April, One week will be in Barcelona. One week... I'm looking for an interesting small town, or region, or chunk of the countryside or whatever. What's interesting? Food, rustic setting, castles to climb around, restaurants, a market once or twice a week, day trips around the area, food, did I mention food yet.
This isn't an art museum and nightclubbing trip; it isn't the trip on which we'll go to El Bulli. This is a live there for a week, enjoy the countryside, eat at the same place three times because we love it and they smile at my kids, have at least a couple of other nice restaurants to choose from too kind of trip. In France I might suggest Aix-en-Provence, in Ireland the Dingle peninsula or Kilkenny. Smaller than the big capitol, but enough going on that we won't exhaust it the first day.
And, as I say, food is a big deciding factor-- not that it has four-star places necessarily, but that the local food is memorable. Where is that perfect place in Spain for what I seek?
