I'm going to Cantabria and Madrid in April and would love to find places to eat without pretension that serve local/regional food -- nothing fancy or innovative. While inexpensiveness is not necessary, it would be helpful to us. In any case the places I am happiest with usually aren't expensive. Atmosphere is completely unimportant. I would love places that are not frequented by tourists, though I won't have a car to get to them. Any thoughts? I'll be in Oviedo, Ribadesella, Torrelavega, and Madrid (I can get along in Spanish if that matters). Thanks so much!
