The Fat Duck restaurant, owned by chef Heston Blumenthal, has been named the UK's best restaurant for the third year in a row.
The Michelin-starred diner was awarded 10 out of 10 by the Good Food Guide and described as producing "world-beating dishes for the bedazzled throngs".
The restaurant, in Bray, Berkshire, beat Gordon Ramsay's Royal Hospital Road into second place.
Raymond Blanc's Le Manoir aux Quat'Saisons, in Oxford, was third.
Ramsay's flagship restaurant was the only London establishment to make the top five of the guide.
L'Enclume, in the Cumbrian village of Cartmel, and Restaurant Nathan Outlaw, in Cornwall, were named in fourth and fifth place by the guide, compiled by consumer group Which?
Elizabeth Carter, consultant editor of The Good Food Guide, said: "Heston Blumenthal and Gordon Ramsay continue to delight us with their stuff of genius, world-class style and truly memorable dining experiences.
"But we've seen significant changes in the UK restaurant scene over the last year.
"A crop of talent has sprung up all over the country, pushing London restaurants out of the top spots with their culinary delights."
Television chef Blumenthal is known for his use of experiments and chemistry to create his dishes.
The tasting menu includes a course called Sound of the Sea, during which the diner eats smoked fish, edible "sand" and "seaweed" while listening to seagulls on an iPod.
