Restaurant Brands International also reported a same-restaurant sales beat for Burger King, marking the chain’s first such beat in six quarters.

Value offers from fast food chains over the past six months have helped attract price-conscious consumers. Burger King, like McDonald's and Taco Bell-parent Yum Brands, has been offering combo options for as less as $5 and $7. The company's Tim Hortons chain has benefited from several quarters of strong growth in revenue, particularly in Canada.
