This new Mayfair spot comes from Iñaki Aizpitarte - the self-taught French-Basque chef behind celebrated Parisian neo-bistrot, Le Chateaubriand. It shares its name with a famous Parisian brothel of the Belle Epoque - and with Kitty Fisher's around the corner, it's in fitting, courtesan-quoting company.
The kitchen is headed up by Paul Boudier - an alumnus of Le Chateaubriand. He has put together a menu influenced by the deconstructed French dishes of the Parisian venue, but which is strong on British produce. Expect it to be a la carte, too - a departure from the fixed menu over at Le Chateaubriand.
The 90-cover room's design comes from Parisian-based architect Clément Blanchet, with a bar offering cocktails inspired by the food and drink of France.
