Tacos Ruben's

"The legend of Tacos Ruben’s is well known across Mexico City. A family-run taquería, this tiny street-side taco cart lures customers from all corners of the city for a taste of the famous taco especial, a combination of suadero, longaniza, and tripe. The tacos are generous, served on standard-sized tortillas (not the shrunken tortilla taquera that’s usually seen in taquerías). The service is extra friendly, though you might want to visit early because the tacos run out fast." - Natalia de la Rosa
