What happens in the food world when a bad employee starts to take down an otherwise thriving establishment or when restaurant owners suspect someone of not doing their job appropriately? They call in the Mystery Diners. These undercover operatives go into restaurants, bars and food service establishments with hidden cameras to find out what's really going on when the boss isn't around.
You can now watch Mystery Diners online on the following streaming providers in the United States.
