Concerns over the impact of steep tariffs and economic growth have dented U.S. consumer spending on eating out, prompting fast-food chains, including Yum Brands, McDonald's and Burger King-owner Restaurant Brands, to launch budget-friendly meal deals to boost foot traffic.

Yum Brands logged higher profit and sales in its latest quarter, driven by growth at its KFC and Taco Bell locations, but still missed analysts expectations.

Lower-income consumers are pulling back visits from QSR concepts across the country, but not at Taco Bell. Not even close. The Mexican giant’s same-store sales rose 4 percent in Q1, outpacing the limited-service category by 4 percentage points.
