Café Tortoni Opens on Avenida de Mayo
Café Tortoni first opened in 1858, started by a French immigrant who named it after a Paris cafe, and became the room where Buenos Aires argued about itself - Borges, Gardel and Rubinstein among the regulars whose likenesses now sit at its tables. It still trades on Avenida de Mayo with its original marble, mirrors and tango cellar.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
