It would be absurd to assess the qualities of a holiday destination solely on the basis of what there is to eat when you get there.
However, if the sun isn't shining, the insects are biting, and the baroque churches are beginning to pall, then the prospect of a splendid lunch is really all that there is to make you want to get out of bed in the morning or to stop you from wishing that you'd stayed at home.
I have to say that from recent experience I have the feeling that in these circumstances northern Portugal is not the very best place in the world to be. It's not that Portuguese cooking is bad; the goat stew is, well, OK, the sardines are nice (though not always properly gutted, and apparently best eaten early in the summer), and we had a few pleasant dishes and a memorable octopus in red wine. But some misconceptions are cherished here: for example, that boiled potatoes and rice, together, are a perfect accompaniment to any meal, that stewed pork is made more exciting if you throw a few clams in with it, and that if you call cod bacalhau it automatically becomes interesting, however boringly you cook it.
So, kind and friendly as the Portuguese people are, there is no denying that their cuisine is among the dullest in Europe.
My wife can be counted on to get the very best out of any situation, but there she could only make a rather sad proposal as we pored over a depressing menu identical with a dozen others we had seen: "We really must investigate the vegetable soup" she said, brightly.
