McDonald's Revamps Classic Burgers for Juicier, Caramelized Flavor.

McDonald's is making changes to classic menu items, including the cheeseburger, double cheeseburger, hamburger, Big Mac, and McDouble burger, with improvements such as softer buns, gooier cheese, and juicier, caramelized taste. The changes are being tested in select US cities and will be the nationwide standard by 2024. The restaurant has also introduced AI at some locations and relied on celebrity meal partnerships for viral marketing campaigns.
