Harish Bharti, the Seattle lawyer who successfully sued McDonald's for using beef extract in its frenchfries and won a settlement for $10 million, is now aiming his guns on another fast food giant. In a proposed class-action suit, filed on April 1 in King County Superior Court in Washington state, which was transferred to U.S. District Court in Seattle last Tuesday, Bharti claims that Pizza Hut used beefproducts in the "Veggie Lover's Pizza" while at the same time marketing it to the vegetariancommunity.
