French Chef Pierre Gagnaire's first venture in London, this enormous 18th-century house has been divided into four different culinary experiences, all extravagantly designed by Mourad Mazouz. The Parlour on the ground floor is a froufrou tea room, with pastries displayed in a jewellery case, while The Glade, the place to go for a light bite at lunchtime, features carpeting in shades of green, thick wooden tables and sunset-red walls.

The Gallery is entirely white and filled with white furniture but has coloured light emanating from the ceiling and a huge frieze of video art; it serves lunch and dinner.

However, the piece de resistance is The Lecture Room, with its dramatic design featuring luxurious padded walls studded with gold - and its dramatic prices. The menu is divided into sections, with a dish or two underneath, so the starters consist of red mullet, vegetables, charcuterie, langoustines and crab. Mains are famed for unusual pairings, the sections include poultry and white truffles, beef and caviar, John Dory and scallops.

Reservations essential. Closed Sunday; The Lecture Room closed Monday as well. Dress code smart / casual.
