White Castle is celebrating National Slider Day this year by offering fans a free slider and small Coca-Cola Freestyle beverage on Wednesday, May 15, 2019.

In order to take advantage of the offer, simply stop by any participating White Castle location on Wednesday, and when you show a special coupon posted exclusively to whitecastle.com on May 15, you’ll score a free slider and beverage on the house.

Additionally, and also on May 15, fans can score two free limited-time BBQ Original Sliders with any purchase when they wear Wild West apparel to any participating location for a limited time during the chain’s ongoing “Western Wednesday” promotion.

BBQ Original Slider

The BBQ Original Slider starts with an Original slider topped with tangy Bulls-Eye BBQ Sauce and crunchy onion crisps, served on a signature bun.



Wild West apparel can include bolo ties, cowboy hats or boots, etc.

The BBQ Original Slider joins the BBQ Brisket Slider and BBQ Impossible Slider in White Castle’s new limited-time BBQ Bash lineup.
