NBC New York reports a salad bar blamed its building after up to eight mice were seen running rampant in its midtown location Sunday night, and said the store was closing permanently next month.

“We closed this store for several days to give our team the Thanksgiving holiday off and did not notice the issue in a timely matter. Rodent activity has been a struggle for the concourse area in general,” Just Salad CEO and founder Nick Kenner said in a statement of the Rockefeller Center location.

Kenner added that the brand would moving out of the underground location entirely at the end of December.

Rockefeller Center owner Tishman Speyer did not immediately respond to a request for comment.

The mice were caught on camera by Eli Colon, who had just finished having dinner at a nearby restaurant about 7:30 p.m. when he saw something moving in the Just Salad.

He said he spotted about six to eight mice running and jumping inside the store, which is closed Sundays, and started to film. “When you see this kind of stuff you get very concerned for the health of the people who work there and the people who have lunch there every day,” he said.

In the video, the mice can be seen scampering around behind the counter in the kitchen. Colon has a 3-year-old with allergies so he was particularly concerned about the level of hygiene. sanitary grade of “A” displays mice like that and we were just passing by not searching for mice and those are noticeable. I’m sure there have to be more. Also questions about the standards and processes used by the sanitary organizations that rates these places and how reliable those are.”
