McDonald's breakfast menu has proved so popular over the years that it's even found its way into popular culture, with the beloved Egg McMuffin featuring prominently in a "Big Daddy" storyline in 1999. But instead of extending breakfast past the 10-a.m. hour, some 24-hour McDonald's locations will start adding breakfast items to their late-night menus.
The Chicago Tribune reported Thursday that the fast food chain has starting testing an "After Midnight" menu, which would serve Egg McMuffins, Big Macs, Chicken Nuggets, hotcakes and a number of breakfast and lunch options from midnight until 4 a.m.
