We're talking about our favorite fast food burgersMatt Huston and Steve Berg prefer Whataburger and April Hill and Steve Knoll are sticking with Wendy's. One KRMG listener sent an open mic that she like the olive burger at Burger Street. Burger King recently made changes to its Whopper for the first time in nearly a decade. The burger now features a more premium, better-tasting bun and a reformulated, creamier mayonnaise. Toppings like lettuce, tomatoes, onions, and pickles are prepared to taste fresher and be stacked more neatly. On the other hand, Sales at McDonald's are down. McDonald's will soon introduce its much-hyped new value menu and a new line of drinks, including a creamy vanilla cold brew coffee.
