The Houston-based Landry's, Inc., which owns around 500 restaurant properties including Bubba Gump Shrimp Co., Chart House and Rainforest Café, reported payment cards used at some of its eateries have been breached.

The company said it is investigating reports of unauthorized charges on certain payment cards used legitimately by customers at some locations. It is unclear how many of Landry's properties were affected.

"We immediately began an investigation after receiving these reports and have engaged a leading cybersecurity company to investigate this matter," the company said in a press release. "We are also working with our processor and payment card networks. We will not know the full scope of this incident until the investigation is completed, and we will work vigilantly to address any potential issues that may affect our customers."
