Cafe Tortoni is Buenos Aires's oldest cafe, having opened in 1858 by a Frenchman. It's always been a haven for famous figures of culture and history. The cafe was the "office" for composers and performers of tango's heyday in the 1920's. Today, it offers the best churros and chocolate in the city, and a very authentic and low-key tango show.

The reason the women are dressed in slinky, sexy dresses, is because in the beginning, the tango was danced only in brothels. It was only after it became popular and approved by Parisians, that it was deemed okay here as well. Little by little, it was accepted, but the dresses became more demure and today the dresses are what we're used to seeing; slinky, satiny, with thigh slits.
