La Caleta Gaditana (CLOSED)

If you want to enjoy perfectly prepared authentic recipes from Cádiz without leaving Madrid (from fried fish to payoyo cheese and 'piriñaca' – an onion, tomato and pepper salad), this restaurant is a must. They just might have the best 'cazón' (dogfish fritters) in the city, but this tasty treat (served in brown paper like other fried items on the menu) is just the tip of the iceberg in such a busy restaurant, the result of the professionalism and dedication of its owners. Despite having moved to a much larger location, it still fills up, so you should book a table in advance at weekends.
