Fodor's Expert Review Café Tortoni

Take a seat amid the Tiffany lamps and marble-topped tables, and contemplate the fact that you may be sitting in a chair once occupied by a former president, a renowned tango singer, or a world-famous artist or writer while they nibbled an exquisite pastry. The place and setting are from another age, thankfully well preserved, but you may have to wait for a table at the oldest—and highly popular—café in Buenos Aires. Reservations are a must for the dinner-hour tango show.
