Concierge.com's insider take:
The heart of San Telmo, formerly the playground of B.A.'s 19th-century elite, is this Spanish-style plaza, the site of several busy open-air cafés and the ever-popular Sunday afternoon Feria de San Pedro Telmo. The bustling bazaara great venue for street-level tango, where dancers throw down plywood boards over the plaza's cobblestoneshosts nearly 300 stalls stacked high with all order of antique Argentine bric-a-brac, from dolls and tango memorabilia to leather goods and gaucho-inspired curios.
