Fodor's Expert Review La Lagunilla

Enormous La Lagunilla has been the site of trade and bartering for more than five centuries. The day to go is Sunday, when vendors set up outside to sell everything from antique paintings and furniture to old magazines and plastic toys. Dress down, and watch out for pickpockets; this is known affectionately as the Thieves' Market—local lore says you can buy back on Sunday what was stolen from your home Saturday.
