This swanky Mayfair restaurant and late night party spot dates back to 1929, but it was quite the place to be when Sir Terence Conran revived it back in the early '90s. It's now under the ownership of the D&D group, and they've spent a small fortune on a refurbishment nothing short of lavish.
There's a modern-European feel to the menu, with dishes ranging from cauliflower velouté with winter truffle to hand-chopped venison tartare with smoked oil, pickled shimeji and sourdough melba, oysters, caviar, Dover sole meuniere and a duck egg bubble and squeak with charred leek, sautéed mushrooms and glazed baby onions.
Keep an eye out for seasonal menus, bites at the bar and fancy brunches, too - including the 'Q Brunch' on Saturdays, with live music, bottomless prosecco and a menu of classic brunch options such as omelette Arnold Bennett, eggs royale or scrambled eggs with lobster and a spinach muffin.
The wine list - slanted toward big-hitting old world regions - is extensive, with many of its bottles available by the glass and the carafe. A wide-ranging champagne selection and an array of classic cocktails are also available.
