My first Grace and Flavour for 2013 is Colbert on Sloane Square, the new all-dayer from Corbin and King, fathers of The Delaunay and Brasserie Zédel, ‘inspired by the great boulevard cafés of Paris’. Red leather banquettes, wood panelling, vintage film posters, tiled floors, bespoke cornicing, plaster friezes, chandeliers, a continuous supply of pain au chocolat and cannelé bordelais, navarin d’agneau, saumon grillé aux champignons sauvages, pan-fried veal schnitzel, steak Diane and croque Provençale. Peruse the menu online and then come to me with your "detox" intentions.
