Buenos Aires is, of course, the world capital of tango, and there is no finer place for learning how to dance cheek to cheek. Opportunities to learn the legendary dance abound throughout the city. At traditional tango venues, like downtown’s Confiteria Ideal, you can sign up for a class and then stay afterward to practice at the milonga (tango club.) Private teachers advertise around the city; they also come to milongas to offer their services to aspiring dancers who need some help on the dance floor. Learning the sultry dance isn’t easy—but it’s hard to imagine a more romantic activity for a couple visiting the city.
