Sidreria El Globo is one of my favorite spots in Gijon. It's located in downtown on a street that runs parallel to the San Lorenzo promenade, close to the main square and Cimadevilla. It's always full of people, so it's better to book in advance. It's a two-story building, with a cider bar on the ground floor and above a space for dining. The decor is simple, and the menu specializes in typical Asturian food with plenty of seafood, cheeses, beans, beef, etc. The desserts are homemade, and as for drinks - they have an extensive wine list, but if you're in Asturias, you really ought to try the cider for which the area is famous.
