'Mystery Diners'

If you're at all suspicious about what goes on around the office when you're not there, this might be a show for you. The premise: suspicious restaurant owners hire "mystery diners" to go undercover and help confirm their worst fears. Tonight's venue: a Las Vegas bistro. 10 p.m. Friday on the Food Network (seattletimes.com/tvlistings).
