The Daily Grind Cafe @ Penn Dental, on the 200 block of South 40th Street, was issued a cease-and-desist order Tuesday morning for failing to have a certificate proving an employee had been trained in proper food handling, according to an inspector's report. When the cafe's manager was reached for comment Tuesday afternoon, two hours after it had been asked to close, the Daily Grind remained open, and the manager said business was brisk.
