Popular fast-food burger chain Shake Shack (SHAK) has hired top British chef Sat Bains.

The catch: It’s just for one day.

On Oct. 9, Bains, who has two Michelin stars at Restaurant Sat Bains, will create 500 orders of a special burger for the restaurant chain, according to Bloomberg. Dubbed the Major Oak, the burger will be served at Shake Shack’s restaurant in London’s Covent Garden.

Bains created the burger with help from Mark Rosati, the New York’s chain’s culinary director. The food item will cost 7.25 U.K. pounds, or $11.33.

As Bloomberg notes:

Made with Shake Shack’s Aberdeen Angus beef patty, the burger is topped with fresh shallots and a slice of Beauvale cheese from Cropwell Bishop Creamery in Nottingham, where Bains is based. Bains also created a forest-inspired ketchup made of seasonal “Penny Bun” mushrooms flavored with pine salt from the needles of local trees, as well as a smoked mayo with a hint of charcoal from the red oaks from Sherwood Forest.

This isn’t the first time Shake Shack has teamed up with a top chef. Last year, the burger chain worked with three-star Italian chef Massimo Bottura, Bloomberg said.

In August, the fast-food chain posted strong sales.
