In the penultimate show of the series, the final four go head-to-head for the chance to take on one of the series' most iconic challenges – Chef's Table.Standing between them and a place in the final three is just one task – their interpretation of a classic dish. It's their last chance to bring together everything they have learned, let their creativity fly and prove to judges John Torode and Gregg Wallace that they are worthy of a place in the final. This high-pressure cook-off will be the end of the journey for one of the four finalists.The remaining three need their wits about them as they depart for central London for the dream chance to work at a restaurant unlike any other, the three-Michelin-starred Core, run by one of the most celebrated chefs in the world, Clare Smyth MBE, who cut her teeth with pioneers Gordon Ramsay and Alain Ducasse.Clare opened Core in 2017, and within three years had achieved the ultimate culinary accolade by delivering the finest British gastronomy, using humble ingredients rooted in nostalgia and giving her food an unmistakeable personal touch but with exceptional flair and skill.The three finalists have never faced anything like this before as they each take on one of Clare's most breathtaking creations for a special lunch for a select group of chefs who are all leaders in their field, including Sat Bains, Tom Kitchin, Jonny Lake and Nieves Barragán Mohacho.Can our three amateurs hold their nerve and reach a three-Michelin-star standard, or will the pressure to deliver be too intense?
