 Last month, McDonald's announced that their U.S. test of the McPlant Burger, developed in partnership with Beyond Meat, did not meet expectations. According to Joe Erlinger, McDonald's U.S. president, the test, which was conducted in San Francisco and Dallas, was unsuccessful. He said the McPlant Burger, which was aimed at consumers interested in plant-based diets, just didn't resonate with McDonald's core customer base.
