Palermo, Buenos Aires
Concierge.com's insider take:
Palermo is B.A.'s largest barrio, and, with its numerous sub-barrios and 350 acres of parkland, it feels like a city unto itself. There's the wonderful Jardín Botánico Carlos Thays with its frisky population of feral cats; the century-old Palermo polo grounds; and the palatial Hipódromo Argentino (4101 Libertador), a thoroughbred racecourse that makes Churchill Downs look like a shotgun shack. But the real action goes down in Palermo Viejo, the hipster hangout centered around Plazoleta Cortázar and subdivided into Palermo Soho and Palermo Hollywood, an area of tipa-lined streets, designer-soap emporiums, cocktail bars, and cutting-edge bistros like the Scandinavian-themed Ølsen. The outlying Las Cañitas is a throbbing nightlife zone popular with pub-crawling yuppies and out-past-curfew teens.
