There can be no doubt that the Lamborghini Waterfall, from Top Banana, is one of the most visually spectacular cocktails ever conceived. In fact, watching its complex construction is nearly as impressive as its pyrotechnic finale.

Into a martini glass is poured an oily concoction of kahlua and blue curacao, two chopsticks are laid across the rim of the glass and above this scaffold is piled a assortment of upside down glasses - first a wine glass, a brandy glass and then a scotch glass, topped off by a shot glass.

This drinking vessel jenga is fun in itself, but the real brilliance happens when Saran the barman pours a double shot of Sambuca into another wine glass and with a flick of his cigarette lighter, sets it ablaze. Reaching on tiptoe, he stretches up and tips a flaming cascade down the glass tower.

The blue flare reaches almost to the ceiling and the cocktail’s unusual moniker makes sense; the turquoise flames resemble a waterfall as they swirl and eddy around the glass.

Saran then empties two shots of Bailey’s into the alcoholic brew at the bottom of the fire and drinkers are provided with especially elongated straws so they can sip from the potent pool, without singeing their eyebrows.

Laurent, the general manager, insists that there have so far been no Lamborghini Waterfall-related injuries, but he confesses that when he first witnessed it, he too “was like, whoa, s*#t!” He says that such is the spectacle, once one has been ordered at the bar, everyone else wants one too.

The taste doesn’t quite live up to the promise of the fireworks, but the unusual mix of the creamy Bailey’s and boozy Sambuca makes for a tasty tipple, reminiscent of a melted chocolate liqueur. This is not a cocktail for savouring at sunset, but after dark it is a measure of dazzling drinking drama.
