K Bar has grown-up sex appeal nailed. Dark wood panelling, cobalt blue bar stools, soft leather and slinky velvet. Boom. Trying to find your best light? Everyone looks on fleek when bathed in the glow of some mega chandeliers.

You can sink into one of the armchairs, but we only ever likes to be in amongst the action. Here it’s perched at the bar, flicking through a menu lit by art-deco lamps. Get flirty with some fizz - there are some killer Champagne cocktails. When we went it was all about the Queen's Gate Orient - sake, Perrier-Jouët Grand Brut, yuzu and sugar. Slinky, sweet, with a bit of a sharp edge. Like us, them. Checking into the hotel so the night lasts a little longer? Make sure you order from the section dedicated to Dessert Cocktails. The Crème Brulée Martini is enough to keep you out that little bit longer.
