This historic cafe has served as the artistic and intellectual capital of Buenos Aires since 1858, with guests such as Jorge Luis Borges, Julio de Caro, Cátulo Castillo, and José Gobello. Waiters gaze over the cafe's antique tables and their occupants with sphinxlike serenity, just as the eyes of the great poets whose photographs line the walls have watched so many come and go. Come in for coffee, or even a simple meal (the food is not the point), and feel Argentine history surround you. The Tortoni is a cultural tradition; there are a number of social events here, including evening tango shows.
