At the border of San Telmo, the Tango barrio of BsAs, the Doppel Bar is said to be the best cocktail place in town. In my opinion, this is very true: a special art noveau environment, perfect music, marvellous cocktails prepared with selected ingredients. The young and wise bartender will bring you along a drinking tour, from classic cocktails to very innovative ideas. By the way, food is also very special. Classic Martini rate: 9/10.
