The current Pétrus restaurant is located in 1 Kinnerton Street, Belgravia, London, where it was opened on 29 March 2010 under head chef Sean Burbidge.

[5] The interior of the restaurant has been designed by the Russell Sage Studio, who also worked on other Ramsay establishments, The Savoy Grill and the York and Albany.

The claret red theme of previous incarnations of the restaurant has been maintained, and was coupled in the design with leather and polished metalwork.

[8] It has been described by Zoe Williams as being distinctly Gordon Ramsay in composition, despite the influences of head chef Sean Burbidge.

[10] A number of pan fried fish dishes have been on the menu, including mackerel with tomato chutney and a niçoise salad, and a sea bream course served with brown shrimp, samphire and an oyster velouté sauce.

[9] Further seafood related dishes include a langoustine and watercress soup entrée which was praised by food critic Jay Rayner.

[18] In 2003, Gordon Ramsay Holdings took over the location previously used by the restaurant Vong at The Berkeley hotel in Knightsbridge, London.

Ramsay signalled his intention to move Wareing and Pétrus into the location after the arrangements between chef Jean-Georges Vongerichten and the Savoy Group were not renewed.

[15] Following the sacking of Hutcheson by Ramsay from Gordon Ramsay Holdings, Hutcheson attempted to take control of Pétrus in its new location as he argued that he had listed himself as sole shareholder of the company "Pétrus (Kinnerton Street)" on the documentation filed with Companies House in April 2010.

[31] Gillian Glover of The Scotsman thought in 2005 that some of the food served was forgettable, but stand out elements included frog leg lollipops which came with her main course of baked seabass with garlic puree.

[9] Fay Maschler visited the new establishment in April 2010 for the Evening Standard, who disagreed with the idea that it was a reopening and said that it instead should be considered to be a new Ramsay restaurant.

Marina O'Loughlin for the Metro in June 2010, thought that the food was fine and although the restaurant seems to have been entirely designed with gathering Michelin stars, it seemed that everything on the menu had been done somewhere else but better.

[33] Time Out's review of the restaurant rated it at four out of five stars, being impressed with the quality of the food and describing the wine selection as "crammed with class".

[40] However, in 2002 editor Simon Wright resigned as he believed that the managing director of The Automobile Association intervened to prevent Pétrus from receiving a fifth rosette at the recommendation of the AA's inspectors.
