In recent quarters, the burger chain's turnaround has taken hold in its home market. Restaurant renovations, sharper marketing and a focus on core menu items like the Whopper have helped Burger King steal market share. Rival McDonald's reported U.S. same-store sales growth of just 0.8% in its second quarter, for comparison. Executives said that they were disappointed by the performance, and McDonald's tapped a new U.S. president to help accelerate its sales. Burger King is also seeing strong results outside of the U.S. Restaurant Brands said international Burger King restaurants saw same-store sales growth of 5.4% during the quarter.But the rest of Restaurant Brands' did not fare as well.Tim Hortons' same-store sales in Canada and overall were essentially flat for the quarter, while Popeyes Louisiana Kitchen reported U.S. same-store sales declines of 5.2%. The fried chicken chain has struggled in recent quarters as more chains compete for a smaller pool of diners, who have grown increasingly value conscious.
