You need to press a buzzer to gain admittance here (a sure way to impress your mates). But a warm welcome awaits at the top of the stairs. There’s a Vivienne Westwood meets laid-back gentlemen’s club feel to the decor. The drinking is all about the cocktails, with legendary mojitos, though the star turn is the aptly named Crown Jewels: a glass of honey-sweetened rare cognac topped with vintage champagne that’ll set you back a staggering £350. Now that really would impress your friends.
