Charcoal Grill, Av. Lázaro Cárdenas

Charcoal Grill on Avenida Lázaro Cárdenas is a Piedras Negras steakhouse built around a genuine piece of culinary history: the original 1943 nacho recipe created by Ignacio 'Nacho' Anaya, who is widely credited with inventing the dish in Piedras Negras. The restaurant serves that original nacho preparation alongside a broader steakhouse menu of rib eye a la parrilla and camarones a la plancha, and has been formally recognized with a Best Original Nacho award for its stewardship of the recipe. This dual identity -- historic dish plus a full grilled-meat and seafood menu -- makes it one of the more distinctive dining stops in this list, since visitors can order the actual dish that put Piedras Negras on the culinary map rather than a generic modern interpretation. The dining room carries a $$$ fine-dining positioning, with a more formal, polished setting than the casual grill houses found elsewhere in Coahuila, and a level of service consistent with a restaurant that draws visitors specifically for its heritage as well as locals for dinner. Reservations are recommended on weekends, when both the historical draw and the quality of the steak and seafood menu bring a steady crowd. The restaurant provides a public website and phone contact, useful for confirming hours or booking directly. For any visitor to Piedras Negras, ordering the original nachos here is considered close to essential, given the dish's direct lineage to this address.
