Walk up the sweeping stairs of the Sainsbury Wing into the resolutely British dining rooms and one feels a world away from the hustle and bustle of the West End. Responsible for many of the capital's coolest dining spots, from The Wolseley to Nobu Berkeley, designer David Collins's touch is evident in the sleek, gentleman's club-style room, complete with granite bar, tub chairs and studded leather banquettes. Ask for a table next to the floor-to-ceiling windows for truly magnificent views.
With an emphasis on upmarket comfort food, this is not the place for a light lunch. Using only seasonal British ingredients, the menu offers treats such as Dorset crab with spring onions and radish, mouthwatering wild Cornish sea bass with peas, little gem and lemon, and school-pudding favourites such as a warm treacle tart.
With a charmingly retro feel, the simple, elegant room and gentle buzz from the slightly ageing clientele create an air of nostalgic sophistication that's guaranteed to impress.
