Beating even the traditional "fine dining" restaurants such as The Clove Club and The Ledbury, which came second and third respectively, Gymkhana in London's Mayfair is the first Indian restaurant to win the award, local media reported.
Inspired by colonial Indian gymkhana clubs, the restaurant blends authentic Indian food and modern British styling and became an immediate hit when it opened in September 2013, The Independent reported.
"It's a testament to the quality of Gymkhana as well as the true diversity of the UK's eating out scene that an Indian restaurant has been named the best place to eat out in the UK," said Stefan Chomka, editor of Restaurant magazine.
National Restaurant Awards in association with Estrella Damm is a Restaurant magazine's annual count down of the top 100 restaurants in the UK.
