Burger King is introducing a new menu item called "King Size Sliders" in a limited-time test across two U.S. cities: Portland, Oregon, and Columbus, Ohio. The test, running from April 14 to May 4, aims to cater to customer demand for variety and flexibility, offering sliders that are larger than traditional sliders but smaller than full-sized burgers. Customers can purchase a "King Size Sliders Box" containing either two or six sliders, with choices from three distinct flavors: Deluxe Slider, Steakhouse Bacon Slider, and Bacon & Cheese Slider, all featuring a flame-grilled beef patty on a soft bun. This initiative follows recent customer feedback efforts by the company's president, Tom Curtis.
