Eating famous street food costs literal pennies
Restaurants in every major and not-so-major city try to recreate the magic of Mexico City street food. All fall short. Ditch the fakes and skip the markup -- the real thing is available on virtually every street corner and caters to every craving. For really, really cheap.
To pick a promising booth, look for a bit of a crowd. To start, sniff around for tacos con chapulines, cochinita pibil tortas, potato chips with chile, lime and Valentina hot sauce, and huaraches (buyer beware, these are HUGE). Google image search anything you don’t recognize. As always, simply pointing at things can get you pretty far.
Street vendors’ sweets are also highly advisable. Look for carts, coolers, or baskets selling churros, paletas/helados (ice cream), condensed milk-covered bananas, and fresh-cut fruit that laughs in the face of the so-called fruits you thought you knew. For the highest concentration of street food options, get lost in Centro.
