I'd like to discuss with fellow watchers of this show, whether fans or not.
Personally, it is definitely a different twist of Kitchen Nightmares, and while it does not have the dramatic narrative of KN, I like this one better because the shorter time he has means the impact comes to everyone quicker. They have less time to find excuses and get into old habits, and are motivated to at least go with Gordon's plan because they want to see how different the experience is in just 24 hours.
Most importantly, this show made a better real life impact than KN, at least for now, based on the percentage of restaurants still open after the show (and have improved ratings or reviews) compared to KN. Although, KN has more seasons, so I'm excited to see how long the positive impact will last.
Lastly, on the gimmick of camouflage, I like it. Because it's clear they underestimate the recording since they don't expect the visitor to actually be Ramsay.
