 In a push to raise the image of its food, Taco Bell last year also introduced a line of "Cantina" burrito bowls that are seen as being more in line with fast-growing rival Chipotle Mexican Grill Inc. Meanwhile, Taco Bell says its lower-calorie "fresco" options, which were introduced in 2005 and come without cheese or sour cream, account for only about 2 percent of sales. Coincidentally, New York Times writer Mark Bittman noted in a feature for the paper's Sunday magazine this past week that the public's relationship with fast food has evolved. "We've gone from the whistle-blowing stage to the higher-expectations stage, and some of those expectations are being met," Bittman wrote in the piece, which argued that the public was ready for a healthy fast-food chain. That doesn't mean fast-food chains have stopped offering more indulgent creations. Earlier this year, for example, Taco Bell rolled out hand-held tortilla-wrapped "griller" snacks; one of the varieties comes stuffed with fried potatoes, a nacho cheese sauce, bacon and sour cream. Its Doritos Locos Tacos have also been a hit, helping the chain grow sales at restaurants open at least a year 8 percent last year in the U.S. Taco Bell has about 6,000 locations in the U.S. The chain is a unit of Yum Brands Inc. of Louisville, Ky., which also owns KFC and Pizza Hut.
