Another legacy U.S. restaurant chain has launched a plant-based burger option. Denny’s is getting creative with the release, offering the burger free of charge on Halloween at locations in L.A.

Get the full scoop from Newsweek here:

Denny’s Beyond Burger was on October 28, in all Los Angeles locations. The burger features a plant-based patty topped with tomatoes, onions, crisp lettuce, pickles, American cheese and Denny’s All-American sauce, inside a multigrain bun.

Customers can try the Beyond Burger for free on Halloween, October 31, between 4 p.m. and 7 p.m. at any Denny’s location in Los Angeles. The burger is free with the purchase of any drink and will be available while stocks last.

Denny’s will launch the Beyond Burger nationwide in 2020. Denny’s has hundreds of locations in all 50 U.S. states and Washington DC, and more than 1,700 franchises internationally.
