From AP News:
Burger King will begin selling the plant-based Impossible Whopper nationwide next week after a successful test run in seven markets.
From next Thursday until September, Burger King will offer delivery and mobile customers two sandwiches – an original Whopper and an Impossible Whopper – for $7 so they can compare them.
The rollout to 7,000 U.S. locations will be for a limited time, a typical practice in the fast food industry for new products. The chain won’t say how many of the soy-based burgers it’s sold since first introducing them in April, but did say it’s enticing more people to enter its stores.
Burger King had been selling the Impossible Whopper in St. Louis, San Francisco, Las Vegas, Baltimore, Miami, Montgomery, Alabama, and Columbus, Georgia, before expanding sales to all of its stores.
