It's apparent why Argentina has long held travellers in awe: tango, beef, gauchos, fútbol, Patagonia, the Andes. The classics alone make a formidable wanderlust cocktail. Arriving in Buenos Aires is like jumping aboard a moving train. Outside the taxi window, a blurred mosaic of a modern metropolis whizzes by, and then the street life appears – the cafes, the purple jacaranda flowers draped over the sidewalks (in spring!), and porteños (residents of Buenos Aires) in stylish clothing, walking purposefully past handsome early-20th-century stone facades. Down it all with that famous Argentine wine, and you'll be struggling to maintain your waistline.
