Salamanca is to Madrid as 5th Avenue is to New York. It is most famous for boutique fashion shops as well as well-known luxury brands. Salamanca’s nightlife mirrors this style with many upgrade restaurants and expensive bars and clubs. If you are looking for a place to sip champagne on a terrace, or a restaurant that transforms into a club in the small hours, this is the place to come. I’ve never had a problem with dress code in Madrid but I assume if there ever was to be an issue this is where it would be. As this is Madrid, of course there are hidden treasures where more reasonable prices and less of a stuffy posh attitude are found.
