18 Oct 2019 --- Burger King’s unveiling of The Impossible Whopper is driving traffic to the fast food chain, according to Barclays analysts. In April, Burger King became a non-meat platform pioneer, testing the Impossible Whopper in 59 St. Louis restaurants before rolling out the meatless burger across US restaurants in August. Now, Barclays data teams have analyzed geolocation data to assess the impact surrounding the test and the national launch. It reveals the preliminary trial generated up to 18 percent gains in the St. Louis locations versus no comparable gains for McDonald’s St. Louis restaurants. And, Burger King has seen a 2 percentage point traffic boost nationally versus McDonald’s with indications that gains have been sustained through to the end of the quarter, according to the analysis.
