"At White Castle, we take tremendous pride in the 2x2 inch sliders we've been serving and perfecting for nearly 100 years," said Jamie Richardson, vice president at White Castle. "We invented National Slider Day as a special tribute to the fans who share that appreciation for the slider and share their cravings with us. We hope everyone will have the opportunity to bite into a tasty slider on May 15."
