Joe's Crab Shack is apologizing after diners discovered a photograph depicting a lynching as table decor in a Minnesota restaurant.

An image depicting the public execution of at least one black person was embedded in a table at the Roseville, Minn. location, USA Today reported. A group of white people surrounded the execution site in the picture.

The caption in the photograph reads: "All I said was that I didn't like the gumbo. Hanging at Groesbeck, Texas, on April 12th, 1895."

David Catalano, COO Ignite Restaurant Group, Joe's Crab Shack parent company, told the news organization the image was immediately removed after it was brought to the restaurant's attention.

"We sincerely apologize to our guests who were disturbed by the image and we look forward to continuing to serve the Roseville community," he said.

Tyrone Williams and Chauntyll Allen noticed the image as they sat down to eat at the restaurant on Wednesday night. They notified the Minneapolis NAACP.

"Although the manager was apologetic about the lynching depiction that does not change the fact that this sickening image of black men being lynched was intentionally embedded inside of a table," Williams told KARE-TV. "This type of blatant racism should not be tolerated in this country, or in our local and national eating establishments. I have felt sick to my stomach and stressed out since seeing that image on the table where I was planning to eat my food."
