Final answer:
Taco Bell attempted to trademark the word "salsafication" in 2001, not Chipotle, which is known for high-quality, responsibly sourced food.
Step-by-step explanation:
The Mexican restaurant chain that tried unsuccessfully to trademark the word "salsafication" in 2001 is Taco Bell. Despite Chipotle being known for its attempts to sell high-quality foods from responsibly sourced providers, which sets them apart from burger chains like McDonald's, it was Taco Bell that sought the trademark for "salsafication". Chipotle's commitment to quality and sourcing differs from the typical fast-food approach, but this trademark attempt is not part of its history. Taco Bell was founded by Glen Bell in 1962 in Downey, California. The first Taco Bell restaurant was a modest taco stand that grew into the global fast-food chain we know today.
