A restaurant inside the Pentagon City Whole Foods is among those affected by a security breach to the company’s credit card system.

Whole Foods provided public notice that it “recently received information regarding unauthorized access of payment card information used at certain venues.”

The breach does not affect purchases within the regular Whole Foods grocery section, but rather at the taprooms and full-service restaurants inside some locations. Paper Horse, a ramen restaurant inside the Pentagon City Whole Foods, is one of the locations named in the security breach.

Whole Foods’ statement said it notified authorities and has launched an investigation. Customers who may have visited Paper Horse or one of the other affected locations listed online should monitor their credit card statements and contact their bank to report unauthorized charges.

Whole Foods also noted that its systems do not connect with those of its new parent company, Amazon, so purchases on Amazon.com are not involved.
