What happened after Mystery Diners?
Mystery Diners' Sept. 25, 2013 episode "Security Issues" (Season 4, Episode 11) featured Del Rossi's Cheesesteak Co. in Philadelphia's Northern Liberties neighborhood. According to an episode overview on TheTVDB, the owners contacted Charles Stiles after hearing complaints about a security guard they had recently hired; the sources reviewed for this entry did not include a full recap of the on-air investigation or its resolution. Wikipedia's article on the series, citing its sources, notes that the show carries a credits disclaimer stating that events may be re-enacted for dramatic purposes, and cites a television critic who described the show's scenarios as implausible and its resolutions as staged.
The restaurant, now branded Del Rossi's Cheesesteak & Pizza Co., continues operating at 538 N. 4th St. A Yelp listing updated August 2026 shows current reviews and photos, the restaurant's own site lists an April 16, 2026 hours update, and the Michelin Guide separately lists Del Rossi's as a 2025 Bib Gourmand selection. The automated check of delrossisrestaurant.com for this entry returned an HTTP 403 error rather than page content, so that domain could not be used as evidence here, but the other 2026-dated sources are consistent with the business remaining open. One Bite Pizza Fest describes in-house seeded rolls and freshly sliced ribeye as signatures of the restaurant's cheesesteaks alongside its pizza menu.
