Full disclosure: It’s authentically tourist-tacky in Plaza Garibaldi, the traditional Mexico City center for mariachi music and culture. But when you’re ready for a serenade, you’re ready. The plaza fills up late at night, every night, with a motley crew of local revelers from all walks of life, plus visitors, vendors, and dozens of extravagantly attired orchestras. Taking a table at Salón El Tenampa, right on the plaza, may afford a modicum of order. A Garibaldi institution beneath its fabulous neon sign, this music hall pulls in a fascinating, Felliniesque crew of misbehaving pencil pushers, shady ladies, brokenhearted tequila swillers, wide-eyed travelers, and slumming hipsters. Strolling bands—usually pretty good—are available for hire, but bring them in close to your table to avoid sonic interference from every other trumpet in the joint.
