Let’s look at the differences between the U.K. and U.S. versions of Kitchen Nightmares

Gordon Ramsey found fame in America by bellowing at slack-jawed line cooks on Hell’s Kitchen, then bellowing at slack-jawed restaurant managers on Kitchen Nightmares. Now, Ramsay saves much of his ire for home cooks on Twitter, with his current TV gig finding him declaring everything “ABsolutely delish-ish” on the adorable Masterchef Junior. It’s the softest we’ve seen the foul-mouthed English cook Stateside, though fans overseas are infinitely more familiar with this version of the celebrity chef.
Kitchen Nightmares originally aired in the U.K. as Ramsay’s Kitchen Nightmares on the BBC, where it won a BAFTA Award. There, Ramsay rarely raised his voice as he helped restauranteurs rethink infrastructure and menu construction. Ramsay narrated the show himself, and sound cues were kept to a minimum. That may come as a surprise to fans of the U.S. version, where Ramsay couldn’t sample a dish without screaming about all the diarrhea he was going to have later.
