Sommelier-turned-restaurateur Xavier Rousset is launching his third solo venture, Comptoir Café & Wine, in Mayfair next month.

It follows the success of Blandford Comptoir in Marylebone – praised in the latest Harden’s Survey for its “superb wine list” – and Burgundy specialist Cabotte in the City, both of which opened last year.

Tucked away behind Bond Street station close to Oxford Street, Comptoir Café & Wine will be open from 8am until late, serving pastries, light lunches and sharing plates in the evening, with up to 30 wines available by the glass.

The wine shop will be in the lower ground floor, with 1,000 wines available, including 100 Champagnes – all of them available to drink upstairs in the 40-seat cafe for the retail price plus £10 corkage.

Rousset became the world’s youngest Master Sommelier in 2002 and was head sommelier at Raymond Blanc’s Le Manoir des Quat’Saisons before setting up London restaurant Texture with Icelandic chef Aggi Sverrisson in 2007.
