The name isn’t just a caprice: this David Collins-designed bar really is as blue as a Billie Holiday album. The sky-blue armchairs, the deep-blue ornate plasterwork and the navy-blue leather-bound menus combine with discreet lighting to striking effect.
It’s a see-and-be-seen place, but staff treat all-comers like royalty, and the cocktails are a masterclass in sophistication. Not everyone can afford to scale the frightening heights of the bar list, worth perusing just to confirm that there is such a thing as a £4,210 bottle of champagne or a £925 shot of whisky (Macallan 55-year-old). Leave those to the A-list, and just enjoy the elegance and luxury of one of the finest hotel bars in the city.
