Russ & Daughters is calling out celebrity chef Nick Liberato for stealing its unique style for a new restaurant.

In a rather scathing Instagram post, the fourth-generation co-owners didn’t mince words. They allege that Liberato, host of the Netflix show Restaurants on the Edge), lifted the in-store experience for his soon-to-open Borscht Belt Delicatessen in Stockton, New Jersey. Signed by Niki Russ Federman and Josh Russ Tupper, the declaration demands a change in design, yet stops short of any public legal threat.

“It is deeply disheartening that you have chosen [to open a business] by copying our iconic design and messaging,” the family wrote. “These are elements that have been intrinsic to Russ & Daughters for 107 years.”

“The design that you copied for your deli does not even come from a deli,” they lambast. “You are copying us without credit, while couching your plagiarism as ‘homage.’”

To that end, Russ & Daughters did not immediately return our multiple requests for comment about any copyright protections it might possess. Or whether a legal battle is brewing.

Dear Nick Liberato,

You recently announced that you are opening The Borscht Belt Delicatessen. We are very supportive of anyone who wants to open a business, especially during such challenging times. However, it is deeply disheartening that you have chosen to do so by copying our iconic design and messaging.
