Great rooftop terrace and drinks. Go to watch the sunset and see 360 views of Madrid.
Point to the fresh seafood you want, and eat standing with a beer.
Incredible atmosphere-- private outside and library lined inside. Food is fresh and unique.
Buy a drink and tapas come with it (potatoes, meats, bread). Great deal and full of locals.
Rich dipping (or drinking) chocolate with hot churros. Open 24 hrs!
So fun. Try a little of everything!
