The Voladores (Totonaca men from Papantla on the Gulf Coast who perfom ancient flying acts) are also your best bet for buying real vanilla pods and vanilla extract in Mexico City.
Just wait for their daily shows outside the Museo Nacional to finish, and ask them 'Tienes vanilla?' For a fraction of the price you'd pay at the tourist shops, you'll get real vanilla, not the essence, straight from the Gulf Coast source.
Los Voladores perform on a platform outside the Museo Nacional, Paseo de la Reforma, Polanco, Mexico City
