Christopher Zucchero says after friend created hit TV show, his Chicago sandwich shop sells more than 800 sandwiches daily

When Christopher Zucchero heard that his childhood friend was writing a television show about his family’s Italian beef sandwich shop in Chicago, he reacted by sarcastically remarking: “Oh, I bet it’ll be a big hit.”

He now acknowledges that he’s been forced to take back his skepticism after the show became the hit FX series The Bear, and business at Zucchero’s Mr Beef shop has boomed like never before, he recounted in an interview Sunday with CBS.
