When first contacted by a reporter Monday about the pending suit, Joy Tsin Lau's owner, Mabel Chi Chan, said she was stunned. She said the health department last visited her restaurant on April 18, two days after the last failed inspection, and granted it permission to reopen. A friend of Chan's provided Philly.com with a copy of the report, which was not yet in the public record. It indicated a clean facility with no violations.
