Cheeseburgers rank among the most loved foods in North America. On September 18, people celebrate National Cheeseburger Day, a tradition that comes only a few months after National Hamburger Day in May.
Hamburgers top the list of favourite American dishes, while cheeseburgers also hold a strong spot. Surveys show that nearly three out of four burger lovers enjoy adding cheese. Americans alone eat about 50 billion burgers every year.
Although the history of the cheeseburger’s origin is debated, several cities claim the title. Pasadena, California, tells the story of a teenage cook who served the first one more than a century ago. Louisville, Kentucky, also claims credit, saying the first “cheeseburger” appeared at Kaelin’s restaurant in 1934.
McDonald’s 50-Cent Double Cheeseburger
To mark the occasion, McDonald’s is offering its Double Cheeseburger for just 50 cents. The deal is available on September 18 through the McDonald’s app. The company said the same promotion last year ranked among its most popular offers.
