NEW YORK - Good news for vegetarians on the East Coast of the United States -- the Impossible Burger is arriving at your grocery stores. The Impossible Burger made a splash last week when it debuted in California -- in its first full weekend sale in Gelson's supermarkets, Impossible Burger outsold ground beef from cows, in terms of both revenue and the number of pounds sold, said Impossible Foods. "The Impossible Burger generated more excitement than any other single product we've seen in more than a half-century of operations," said Gelson's CEO Rob McDougall in the press release. The Impossible Burger debuted three years ago at Momofuku Nishi, a high-end restaurant in New York City owned by chef David Chang. Now, the Impossible Burger is served at over 17,000 restaurants, including Burger King and White Castle.
