Taquería El Califa de León

Taquería El Califa de León is a taqueria in Colonia San Rafael, Cuauhtémoc, Mexico City. It was founded in 1968 by Juan Hernández González. Its menu is limited to a small variety of beef tacos made with hand-made tortillas. The restaurant received a Michelin star in 2024, the first Mexican taco stand so awarded.

History
The restaurant was opened in 1968 by Juan Hernández González and is named after the nickname of bullfighter Rodolfo Gaona. Most of the restaurant's small footprint—variously cited as 100 ft2 or 50 m2—is dominated by the large grill while customers cram into the other half, where there is no seating. The sidewalk outside is occupied by street vendors, further limiting capacity.

A noted regular in the 1980s and early 1990s was Luis Donaldo Colosio, later a Mexican presidential candidate who was assassinated in 1994. Framed on one wall is a 1993 column from the newspaper Ovaciones in which the author recounts running into Colosio and states, "[i]t's the most egalitarian eatery in Mexico. Everyone eats standing, dripping salsa on the stools, whiffed by sleepless dogs." Other politicians, including Eruviel Ávila, Miguel Ángel Osorio Chong, Humberto Moreira Valdés, and Carlos Salinas de Gortari, were known to be regular customers; the restaurant is four blocks and 650 m, nine minutes' walk, from the national headquarters of the Institutional Revolutionary Party (PRI).

The name "El Califa" was never trademarked, and a 15-unit taco chain in the Mexico City area is also known as El Califa. In 2017, the stand reported that it had struggled since operator and founder's son Mario Hernández Alonso's death in 2002 due to competition with other taco stands, security issues in the area, and the cost of the dishes.

Menu
The menu has remained much the same; Hernández González told his son, Mario Hernández Alonso, that it was not worth expanding because "avarice rips the bag". Its signature taco, the Gaonera, is named for Gaona; it is one of three items on the menu, alongside steak and rib tacos. Tacos are prepared with handmade tortillas. Drinks are soft drinks or juices. The Gaonera taco, the most popular taco at the stand, is made from a tender, juicy filet mignon steak that is grilled with a little grain salt and a few drops of lime. Diners can season their orders with salsa verde or roja.

Reception
In Marco Beteta's opinion, the hand-made tortillas and tacos were excellent and well worth the price. Writing for the Los Angeles Times, Alonso Ruvalcaba listed El Califa de León as a place to go for tacos.

On 15 May 2024, El Califa de León was awarded a Michelin star—indicating "high-quality cooking, worth a stop"—the first time a Mexican taco stand had received such a distinction. The announcement praised the Gaonera's beef fillet and corn tortillas as an "elemental and pure" combination. The news caused crowds and long lines to form outside the restaurant. As a result, the restaurant's revenues increased, it employed additional staff members, and adjacent businesses profited.
