White Castle has launched a new website that highlights its devotees via viral videos and such. You can download a coupon for a free slider at the new WhiteCastle.com, but more valuable is the knowledge you’ll glean there. Things we didn’t know till today: White Castle sells coffee online. White Castle has a cookbook featuring “innovative recipes.” White Castle sells shower curtains and $125 corn-hole sets (because there’s just something about sliders that makes you want to toss bags of corn feed through an expensive hole). And — no joke — White Castle has its own version of a Snuggie, called a “couch pouch.” Somehow it didn’t make our foodie Christmas list.
