White Castle, often considered America’s first fast food restaurant, is celebrating National Slider Day on May 15 with a special offer for its loyal fans. Known for its iconic mini burgers, White Castle has been serving up its famous sliders since 1921, making it a true pioneer in the fast food industry.
Although White Castle may not dominate the market like it once did, it remains a regional favorite, especially for those who crave the signature steamed sliders topped with pickles and minced onions. The fast food chain has become a staple for late-night snackers and burger enthusiasts alike.
In honor of National Slider Day, White Castle is giving away free sliders to customers who download the app. By using the code SLIDERDAY at checkout, customers will receive one free original slider.
Additionally, White Castle is offering a six-slider deal for just $4, bringing the price of each slider to just 67 cents. This promotion makes it easier than ever to enjoy the beloved mini burgers at an unbeatable price.
Though nothing would top a year’s worth of free sliders, fans of White Castle can still celebrate with these fantastic deals.
