Several diners reported recently seeing rats in Trio, a popular restaurant in Palm Springs, and have posted their complaints on the review websites Yelp and TripAdvisor.

Tony Marchese, Trio co-owner and general manager, said Tuesday that the sightings in October were a “one-time incident.” An overgrown palm tree had broken holes in the roof, allowing rats to enter the restaurant, said Marchese, who runs the business with owner and chef Mark Van Laanen.

“It happened once, and it’s all been taken care of,” said Marchese, who added he was not in the restaurant during the sightings. “It’s all been sealed up.”

Officials from the Riverside County Department of Environmental Health said Tuesday that they had no record of any complaints in October about rats in the restaurant.

Trio, which serves California contemporary cuisine, has received an “A” grade during routine health inspections every year from 2009 to the most recent one on Sept. 16, according to online county records.

Several Yelp users wrote posts on Oct. 17 and Oct. 22 about rats running across ceiling pipes and falling from the ceiling, with at least one landing on an empty table in the outside patio.

“But once dinner was over, and we had paid the bill, we noticed there was a big RAT scurrying across one of the ceiling pipes,” Yelp user “Jen C.” wrote. “Now that all eyes were on the ceiling, we noticed three more rats.”

Another Yelp user, “BJ S.,” said he saw five rats fall from the ceiling. “It was absolutely shocking,” he wrote.

Marchese posted these comments on TripAdvisor in response to one customer’s post:

“I am so sorry and upset about this situation that happened when you were in for diner (sic). We are top rated restaurant, with perfect health inspections, and nothing like this has ever happened in the 5 years we have been in business. This is not a cleanliness issue. I had people out today to help figure it out and was told that rodents live in our palm trees and there is one next to Trio. They apparently got on our roof and that’s how they got in. This issue has been taken care of , and I embarrassed and with all my heart and truly sorry for your experience. I invite you back to try to Trionagain some time and it would be my pleasure to buy you and your guests dinner. Again, my deepest apologies, Tony.”
