What happened after Mystery Diners?

On the Season 8 episode "Memorabilia Mayhem" (Mystery Diners, aired 2014-12-01), Michael, owner of Rock Island Cafe in Honolulu, grew concerned about a drop in sales of the memorabilia and collectibles the diner displayed alongside its food, and he asked investigator Charles Stiles to send in mystery diners. The undercover team reported finding staff using the cafe for personal business during shifts rather than attending to customers and inventory. According to Wikipedia's article on the program, citing its sources, the show's own end-credits disclaimer allows that certain events may have been staged or re-enacted for dramatic effect, and a television critic quoted in the article described the show's setups as unconvincing. Rock Island Cafe, a retro-style diner on Kalakaua Avenue in Waikiki known for its Elvis Presley and Hollywood memorabilia collection displayed throughout the dining room, was marked permanently closed in Google's business listing for the address, and a Yelp listing for the diner, updated in July 2026, likewise marked it permanently closed with no current hours, menu, or photos posted. This review did not locate a dated news account naming a specific closure date, and the cafe's own website, unchanged since a 2015 copyright notice, made no reference to closing or to any final open date. No relocation, reopening under a new name, or successor business was found for the Kalakaua Avenue address in the sources checked here.
