Artesian

Named number one of the World's 50 Best Bars four years running, Artesian owes much of the recognition to its inimitable head bartender, Alex Kratena, who is both charismatic and creative. The unusual is the usual here, with ingredients like kale, curry, mushrooms, and frankincense used throughout the creative cocktail menu. Located within the Langham Hotel, the décor is five-star elegance, with low-slung chandeliers and regal plum-colored seating. Other accolades here include London's most exhaustive rum collection and an impressive list of Champagne brands on offer.
