White Castle holds a unique place in American fast food history. While McDonald’s is often credited with shaping the modern quick-service restaurant (QSR) industry, White Castle was actually the first fast food restaurant in the United States. The chain began serving its signature sliders in 1921, long before McDonald’s opened its doors. Many credit White Castle with making the hamburger a central symbol of American culture.
Though its presence has diminished over the years, White Castle remains a beloved regional favorite. Known for its small, steam-grilled burgers topped with pickles and minced onions, the chain continues to attract loyal fans. Its unique menu items, like chicken rings and customizable sodas, have helped maintain its popularity, especially among late-night visitors.
In celebration of National Slider Day, White Castle is offering customers a special promotion. On May 15, guests can receive one free original slider by downloading the White Castle app and entering the code SLIDERDAY at checkout. This offer provides a simple and cost-free way for fans to enjoy the chain’s most iconic menu item.
Additionally, White Castle is promoting its recently launched value deal. Customers can purchase six original sliders for just $4, bringing the price per slider down to approximately 67 cents. This limited-time offer aims to provide an affordable option for customers looking to enjoy a larger order.
While the idea of free sliders for a year might be wishful thinking, these current promotions offer a satisfying alternative. Fans are encouraged to take advantage of the deals while they last.
