Charcoal Grill, Calle Once

Charcoal Grill on Calle Once is the more casual second Piedras Negras location of the restaurant tied to the original 1943 nacho recipe of Ignacio 'Nacho' Anaya, offering the same heritage dish in a less formal setting than the flagship Avenida Lázaro Cárdenas branch. The menu keeps the original nachos as the centerpiece, joined by tacos de arrachera and costillas BBQ, a slightly more casual, grill-and-street-food-leaning selection than the full steakhouse menu at the main location. This branch is priced at the more accessible $$ level, positioning it as the everyday version of the Charcoal Grill name for locals and visitors who want the historic nachos without the fine-dining pricing or formality of the original address. The dining room is simpler and more relaxed -- casual seating, no dress code, and a livelier, more come-as-you-are atmosphere suited to a quick lunch or casual dinner in Zona Centro. There is no reservation requirement here, reflecting the branch's positioning as a walk-in-friendly, everyday option. A listed phone number allows for calling ahead to confirm hours. Because both Piedras Negras locations serve the same original nacho recipe, visitors short on time can choose whichever branch is more convenient without missing the dish's core heritage appeal, while those wanting the fuller steakhouse experience should head to the Lázaro Cárdenas flagship instead.
