Adding some extra pizzazz to Sloane Square, this bijou basement pleasure pit is done out in rocking Tijuana ghetto chic. The fun starts with early-evening cocktails and tapas, before thrill seekers trickle in for late-night parties, turning Tonteria into Tatleria as the glossy gossip-column posse hits the floor. Tank up on Tequila firefly (Cazadores Blanco, lime, passion fruit and raspberries) or frozen margaritas. Overhead, the Tequila Express – a Wild West-style locomotive – rides a miniature railway track, dispensing shots. Meanwhile, hedge-funders can splash out on Mayan pyramid – a showboating, three-Tequila celebration punchbowl ablaze with a ‘river of fire’.
