Roll'n Lobster Food Truck Is Now Lobster Zen — Mystery Diners Update

Mystery Diners (Food Network) investigated the Roll'n Lobster Food Truck, a Los Angeles-area lobster food truck, after owner Peter noticed excess lobster meat missing and unexplained extra mileage on the truck and suspected new drivers of running personal errands with it. Wikipedia's article on the series describes Mystery Diners as an operation run by host Charles Stiles that goes undercover at restaurants and food trucks, at the owners' request, using hidden cameras and staged interactions to document suspected problems. According to Food Network's description of "Food Truck Fiasco" (aired April 24, 2014), Mystery Diners investigators Shelby and John went undercover to watch the drivers; the available description covers the setup of the investigation but does not detail what Stiles told the owner afterward or what change followed.

Wikipedia's article on the series, citing its sources, separately notes that the program carries a disclaimer that certain events were re-enacted for dramatic purposes and describes a television critic's assessment that some of the show's scenarios and outcomes can appear implausible or staged. The truck's Google Places listing now carries the name Lobster Zen at a Rosemead, California address, and a check of the associated website, lobsterzen.com, on 2026-09-08 found a server last-modified date of June 2, 2026, posted weekly hours, and an active online-ordering and newsletter sign-up section. Google's Places listing separately lists the business as operational.
