This restaurant is in the famous Gascon, the street with all the cider houses in Oviedo. You can taste some of the best Asturian cuisine like bean stew, soups, cheese sausage, toast with picadillo, all accompanied by good cider. There is also a shop where you can buy local Asturian produce. I recommend ordering the Asturias plate for 4 people and nothing else. You'll get very, very good food. There's another larger restaurant just outside Oviedo, in Colloto.
