The Best Tacos in Mexico City Can Be Found at These 19 Taquerías | Eater

"The most famous downtown taquería, Los Cocuyos keeps up an impressive operation 24/7 as diners gather on the short plastic stools on the curb at all hours. The shop specializes in suadero (brisket) and tripe cooked in a bubbly meat jacuzzi, as well as tacos de cabeza (steamed cow’s head). The Cocuyos technique is very basic; the tacos are cooked in lard confit seasoned just with salt, no herbs, and the master taqueros work patiently as they stir the cauldron, chop ingredients, and serve tacos until the pot is empty, usually around 3 or 4 a.m. Their tripe is one of the best in the city (soft yet crispy, oh so savory, never chewy), making Los Cocuyos an obligatory visit for any taco enthusiast. As of late, expect long lines around evening time." - Natalia de la Rosa
