In recognition of National Slider Day – White Castle‘s self-proclaimed holiday celebrating The Original Slider — the burger chain will be giving away Cheese Sliders in restaurants on Monday, May 15, 2023.

To take advantage of the in-restaurant offer, simply show this digital coupon at any participating location on Monday – no purchase required. It’s also my understanding that many locations will not require the coupon to take advantage of the giveaway, simply mention the promotion.
White Castle’s Cheese Slider features the brand’s Original Slider, made with 100% beef, steam grilled on a bed of onions topped with a slice of American, Jalapeño or Smoked Cheddar cheese.
