27 Bruton Place, London W1J 6NQ
This restaurant is headed up by chef Larry Jayasekara, previously head chef at Petrus. It's set in an absolutely beautiful space, adorned with artwork throughout. It's a fine dining affair with much of the produce coming from the Rowler Estate in Northamptonshire. Expect intense attention to detail in the cooking and make sure to try one of their pies if they're on the menu. Also note, the same team is behind The Rex Delicatessen across the road, which is well worth a look.
