The Choco Taco is coming back, and you’re going to have to be really lucky to get it. To celebrate Taco Bell’s 60th anniversary, the beloved fast-food chain is partnering with Klondike—conveniently enough, a company celebrating its 100th anniversary—to release the iconic desert taco once again, but there’s a catch. The new batch of Choco Tacos is only going to be available at 20 Taco Bell locations as supplies last.
