# Mystery Diners

Mystery Diners is an American reality television series that aired on the Food Network from May 20, 2012, to April 27, 2016. The series is hosted by Charles Stiles, the owner of California-based Business Evaluation Services and Mystery Shopper Services.

## Plot

The show focuses on the Mystery Diners, an organization led by Charles Stiles that goes undercover at specific restaurants at their owners' requests, and sets up undercover stings and unseen surveillance cameras to catch misbehaving restaurant employees in the act.
Season 9 had Charles Stiles starting to make use of private investigators.

## Controversy around authenticity

A disclaimer at the end of the credits reads "The people and events depicted in this program are real. Certain events may have been re-enacted for dramatic purposes."
Television reviewer Ben Pobjie wrote "Mystery Diners has achieved enormous success on SBS Food Network despite making no attempt whatsoever to appear convincing. This show, which purports to 'expose' employees of restaurants ripping off their employers, contains so many implausible scenarios, inept actors and transparently fake denouements that it's really quite refreshing."

| Kitty Hernandez, owner of Breuckelen Colony in Brooklyn, becomes suspicious after receiving complaints from her customers about receiving parking tickets, as her restaurant has a contract with a valet service, Vic's Valet. Kitty has also been noticing upswings in her water bills. She gets even more suspicious when Charles' private investigator Daniel reports that her contract with Vic's Valet was terminated two months earlier, but two valets from Vic's Valet named Sly and Paul are still working outside the restaurant and have no permits with the city or business licenses. Upon calling Vic to learn about when the contract for the valet service ends, Kitty learns from Vic that her manager Mark had already terminated their contract (which he did not have the authority to do). Kitty tells Vic that she will rectify this when they meet in a few days. With Daniel observing the valet service from a chase vehicle and Mystery Diner Jamie going undercover as a customer, the team discovers that, since Sly and Paul no longer work for Vic, they are parking cars in locations away from the restaurant where parking is prohibited and running an illegal car wash service with help from some unidentified servicemen which explains the water bill upswing. Sly is also seen disposing parking tickets issued by the meter maid. The matters are made worse when Kitty learns that Mark is the one behind the scam and has also been responsible for stealing citrus fruits and other ingredients to make the carwash business "organic". After a car gets towed away, Kitty brings Mark back to the control room for the confrontation, during which she fires him. In his exit interview, Mark claims he was doing a good deed for Kitty's business while stating the car wash service was a "visionary thing". Kitty thanks Charles for his help and plans to rectify what happened with the contract to Vic's Valet. The narrator reveals that Mark has not returned the Mystery Diners' calls to him. Sly and Paul were terminated from Vic's Valet. The car wash servicemen have not returned. Kitty has reinstated her contract with Vic's Valet to handle the valet service. Kitty is no longer getting complaints and her water bills are back to normal. Mystery Diners: Jamie. Private Investigator: Daniel. Targets: Mark, Sly, Paul. ||||||

| Manny Martins, owner and head chef of Spanish Potato Grill in Brick Township, New Jersey, is planning on relocating his restaurant to a bigger location across town, but has been noticing theft and vandalism taking place at the new location while it is under construction, leading to the day of the grand reopening getting postponed again and again, as well as a decline in customers at the current location. Manny's main suspects are his manager Toni, who, aside from him, is currently the only one who has access to the new location, and his sous chef Franky, with whom he has had arguments. Charles' private investigator Daniel reports that he has seen Franky making a deal to open his own restaurant with a realtor, leading Manny to believe that it will be a Portuguese restaurant and that Franky will steal his recipes, too, since he has access to them. With Mystery Diner Megan going undercover as a waitress and Daniel staking out the new location, Toni is shown to be a model employee, and, like Manny, she believes that Franky is not qualified to run his own restaurant. The decline in customers is then revealed; hostess Crystal is seen lying about not having any openings at the restaurant, directing the customers to Franky's unopened new restaurant, and terrorizing them by pulling the fire alarm. Meanwhile, waiter Bryan is seen breaking into the new location, spray-painting "Manny sucks" on the wall, and smashing vases while stealing the POS system that is soon to be installed. Daniel is able to catch Bryan trying to leave the scene and put him under citizen's arrest. Bringing him back to the restaurant's current location, Manny then collects Crystal and Franky. During the confrontation, with Daniel lingering by to be ready to take Bryan to the arriving police car, Manny gets angry at Franky and attempts to attack him, forcing Charles to restrain him. Crystal claimed that she smelled smoke, and thought there was a fire. Manny disagrees with her claims by pointing out that he didn't see any smoke or fire in the restaurant, and fires all three of them. Manny then invites Charles for a dinner cooked personally by him. The narrator reveals that Franky lost his lease on the building he acquired and has been unable to secure a new location. Bryan was contacted by the authorities and has returned the items he stole. Crystal still maintains no wrongdoing and has found employment elsewhere. Manny has successfully relocated Spanish Potato Grill and business there has never been better. Mystery Diners: Megan. Private Investigator: Daniel. Targets: Franky, Crystal, Bryan, Toni. ||||||

| Richard and Marilyn Schlossbach, sibling owners of Langosta Lounge in Asbury Park, New Jersey, are concerned about a discrepancy in their lobster supply. Mystery Diners Megan and Natale go undercover as a waitress and a customer, and discover different things happening; manager Diane is seen having her own order of lobsters at the bottom (fortunately, she is paying for them out of her own pocket and has the receipt to prove it). Even though efficient with her job, waitress Sam is seen promoting her own swimsuits to female customers in to-go bags while in cahoots with Eva, who is the manager of the Lightly Salted Surf Shop next door (which Marilyn owns as part of their property), with the purchasing being cash only. The lobster discrepancy is then revealed where waiter Mikey is revealed to be a lobster activist as he is seen lying to customers about the restaurant having no lobsters left, badmouthing the consumption of lobsters, and stealing lobster traps from the marina, as confirmed by Charles' private investigator Dennis. Mikey is also seen stealing lobsters from the lobster tank. During the confrontation, Mikey states that saving lobsters are more important to him than facing the consequences of doing so, but the owners fire him and let Sam and Eva go from their employment. Before Diane can prove she stole nothing, the owners see footage of Mikey fleeing to the beach in his latest attempt to preserve the lobster population, leading Charles and Dennis to chase after him and successfully stop him. Marilyn states that they are at a loss of words for what he saw and Richard orders Mikey to leave the property with Dennis escorting him away to possibly turn him over to the police. Richard and Marilyn thank Charles for his help and plan to cook him a lobster dinner. The narrator reveals that Mikey remains unapologetic in his plans to preserve the lobster population. Without their own location, Sam and Eva were unsuccessful at selling their own swimsuit line. Diane was let off with a warning and no longer orders lobsters for her own consumption. Lobster sales are back to normal. Mystery Diners: Megan, Natale. Private Investigator: Dennis. Targets: Diane, Sam, Mikey, Eva. ||||||

| In a Mystery Diners first, two of El Toro De Oro's waitstaff Bryan Cid and Jessica Rubenstein in Maywood, California, hire Charles to see if horrifying accusations made against general manager Ryan are true, with the help of the restaurant's new owner Xavier Franco (who came in from Las Vegas and was friends with Ryan). Because Xavier is a hands-off owner, the team could not set up the hidden cameras and microphones without raising suspicion as explained by the narrator. Therefore, the cameramen and audio technicians had to pose as customers. Charles' makeup artists give Xavier a foolproof disguise so that he and Charles can pose as customers and conduct the sting from inside the restaurant. Senior Mystery Diner Amanda is also there posing as a customer with her date on the patio. Bryan and Jessica also go undercover as Mystery Diners which marking the second time on the show since "Very Bad Bosses" where actual restaurant employees appear as the Mystery Diners. Xavier gets a good look at the abuse that Ryan is giving to his male waitstaff and busboys; he does not even have shift manager Stew properly train the new employees. Amanda tests Ryan's managerial skills by smashing a plate of food on the floor, and having busboy Julio clean it up, which he was not trained to do. On top of that, he is also seen giving his girlfriend complimentary meals, allowing her to take paychecks, even though she is not an employee, and sexually harassing the female waitstaff. When Ryan is caught verbally abusing Stew, Amanda escorts Ryan to the restaurant's parking lot for the confrontation where Xavier removes his disguise and scolds Ryan for the oppression he has caused with the entire restaurant staff. Ryan thought his actions was helping Xavier in handling the business, but Charles and Amanda disagree. Charles and Xavier have evidence of his abuse that is not only hurting morale in the restaurant, but also chasing customers away. Xavier fires Ryan and ends their friendship, stating that Ryan has not grown up at all. After Ryan departs, Charles and Amanda suggest to Xavier that he should let his staff know that he appreciates them and that he should promote one of his loyal staff members as general manager. The narrator reveals that Ryan has been unsuccessful at mending his friendship with Xavier. Ryan's girlfriend has not returned to the restaurant and her last paycheck was cancelled before she could cash it. Stew has been promoted to general manager. Workplace harmony has returned and employee morale has never been better at El Toro De Oro. Mystery Diners: Amanda, Bryan, Jessica. Targets: Ryan, Stew. Note: Because of how the sting was operated, no private investigators were used in this sting. ||||||

| Tony Rivoli, owner of Rivoli's in Toms River, New Jersey, begins to believe that his new meat purveyor Eric is selling him stolen goods after noticing a significant decrease in order prices.

In addition, they are also shown to have zero tolerance for mispronouncing the restaurant's name. Meanwhile, Charles' private investigator Daniel does a background check on Eric (whose last name is bleeped) and reveals he is an ex-con where he did time in prison for three years from 2009 to 2012 for aggravated assault and is also wanted in Pennsylvania, Massachusetts, and Delaware. Eric also gave Tony a business card for a meat-packing company that the team discovered was bogus (the address was for an abandoned warehouse). Later, Daniel drives over to Eric's house where his delivery truck is and Eric's driver Les comes to pick him up. Daniel follows them to another abandoned building where another delivery truck is waiting. The team finds out that the meat being sold for low prices was actually from another meat-packing company with a delivery which they received from a truck driver named Omar. After they witness Omar trying to end Eric and Les' deal only to be roughed up by them, Charles asked Daniel to call the police and to have them meet him at the restaurant. Meanwhile, Danny's cover is blown when the staff discover that he has a wire on him, but Tony runs down there and clears things up with them. He then brings Eric and Les to the control room for the confrontation during which the two police officers arrive at the same time and place handcuffs on the two culprits. Tony terminates his business relationship with Eric and Les who are then taken away by the police officers. Happy that none of his staff and family were involved in Eric and Les' scheme, Tony thanks Charles and plans to cook him a pasta dish. The narrator reveals that Eric and Les are currently awaiting trial while no longer providing meat to anyone. The other meat packing company was informed of the scheme and Omar was terminated for his involvement. Tony rehired his old meat purveyor and his meat prices are just right. Mystery Diners: Danny.
