Tijuana rewards visitors who look past its border-town reputation. Yes, Avenida Revolución is loud and kitsch, but a few blocks away lies Zona Río, a neighborhood of world-class restaurants and galleries. The city invented the Caesar salad, houses a world-class cultural center, and contains one of the most photographed folk-art sculptures in North America. It's a city of invention and hustle — border culture at its most creative.
