It's the latest legal skirmish between Sarkis owner Marla Cramin and her brother Scott Jaffe, who managed Sarkis for about a decade. The lawsuit — filed Wednesday in Cook County Court against Jaffe, his wife, Debra Jaffe, and the Uptown Diner LLC — claims the Jaffes "copied Sarkis' entire menu and began serving the exact same food items as Sarkis" and were "misrepresenting to the public that Uptown Diner is affiliated or related to Sarkis."
