What happened after Mystery Diners?

Mystery Diners' episode 'Heavy Lifting' (Season 6, Episode 12), which aired 2014-06-23, examined service or staffing practices at Protein House, a fast-casual eatery in Las Vegas, Nevada. Following the show's usual format, host Charles Stiles relied on hidden-camera surveillance to document the issue under investigation, then presented the footage to the owner and discussed steps to correct it going forward. According to Wikipedia's article on Mystery Diners, citing its sources, the program includes a disclaimer that certain depicted events may be re-enacted for dramatic purposes, and a television critic referenced in the article described the show's scenarios and resolutions as implausible and staged-seeming. PROTEINHOUSE's own website, at protein-house.com, was last modified on 2026-08-12 and carries a 2026 copyright notice, current hours for its locations, and an active online-ordering system. The site's locations page lists a Las Vegas location matching the Rainbow Boulevard address that Google Places records as a currently operational business. The website also promotes the brand's meal-prep, catering, loyalty rewards, and franchising programs as ongoing offerings, and the chain, which operates multiple locations across several states, continued to list Nevada among its active markets as of the August 2026 site update. No closure notice, delisting, or conflicting report was found for the Rainbow Boulevard location.
