Ten con Ten Restaurant has become the place to see and be seen in Madrid. You are not in the loop if you have never been there. And surprisingly food is good and prices are sensible.
The down side is the real hard time you’ll have trying to book a table, especially for weekends. But do not give up and try, if you cannot get to have a table at the restaurant you can always have a drink and finger food at the crowded, noisy and amusing bar. You’ll get the perfect flavor of the place!!!
