Burger King's sales rose during the first quarter, boosted by the addition of hot dogs to the menu in the U.S.
Parent company Restaurant Brands International Inc. said Burger King's global sales jumped 4.6 percent established locations, including a 4.4 percent increase in the U.S. and Canada.
CEO Daniel Schwartz declined to specify how much of the sales increase in the flagship U.S. market was driven by an uptick in customer visits, versus higher spending per visit. But he said the hot dogs, introduced in February, were helping bring in new customers and driving up spending among existing customers who tack hot dogs onto their orders.
