PHILADELPHIA (CBS) – A number of Philadelphia’s most popular restaurants are under scrutiny.

On Wednesday, the U.S. Attorney’s office for the Eastern District of Pennsylvania announced it has “launched a review” of 25 of the city’s most popular restaurants to decide whether they’re in compliance with the Americans With Disabilities Act of 1990.

Some restaurant owners will have to complete a survey on their restaurant’s accessibility, and inspectors could perform on-site inspections to confirm those survey responses.

If a restaurant isn’t compliant, its owners can agree to upgrade the premises to meet ADA requirements. If the owners fail to upgrade or are found to be “engaging in a pattern or practice of discrimination,” however, they might find themselves at the center of a government lawsuit.

The U.S. Attorney’s office says the review is not the result of a complaint against a specific restaurant, and states that it used third party restaurant rankings to review some of the city’s “most popular and frequented restaurants.”
