The popular but troubled diner Gladys Knight Signature Chicken & Waffles scored a low failing grade of 44 on a recent health inspection.

Roaches and fruit flies, as well as grease and dirt build-ups, were noted on the Peachtree Street restaurant’s inspection, which happened last Thursday.

Under Georgia law, the restaurant will be inspected again within the next 10 days. Another failing grade could lead to Chicken & Waffles being shut down temporarily to fix the problems or even having its license revoked.

Gladys Knight has filed a lawsuit to have her name removed from the chain of restaurants now run by her son, Shanga Hankerson. Hankerson has refused.

That move came after federal revenue officials conducted a June raid at all locations of the restaurant and its corporate headquarters.

The Department of Revenue has opened an investigation of Hankerson, alleging he has failed to pay more than $650,000 in sales and withholding taxes.
