Riemma Kitchen Warehouse Is Now The Kitchen Store — Mystery Diners Update

On "Secondhand Scam," the Mystery Diners episode that aired 2015-11-25, the owner of Riemma Kitchen Warehouse, a kitchen-appliance seller in the Los Angeles area, told Charles Stiles that customers were finding food left inside factory-sealed appliances and asked him to investigate. Stiles's undercover team traced the problem to how incoming returns and floor units were being handled and reported back to the owner, who removed the staff responsible and, consistent with the show's usual format, was advised to change how open-box and returned appliances were inspected before resale. Wikipedia's article on Mystery Diners, citing its sources, notes the show discloses that some scenes are staged or re-enacted, and a television critic has called several of its scenarios implausible.

The address given for this business, 6322 West Slauson Avenue, is in Culver City rather than Los Angeles proper. It no longer operates as Riemma Kitchen Warehouse. Google's place record lists the address as operating under the name The Kitchen Store, and that business's own website, thekitchenstore.net, was last modified in July 2026 and described the business as a kitchen design and cabinetry showroom rather than an appliance retailer. It is not established from the sources reviewed here whether The Kitchen Store is a continuation of Riemma Kitchen Warehouse under new branding or an unrelated business operating at the same address.
