Gigi's restaurant created the drink for actress and singer Grace Jones

A new London restaurant is selling what could be the most expensive cocktail in the world, setting drinkers back almost £9,000 per glass.

Gigi’s, in Mayfair, created the signature drink for actress and singer Grace Jones, who appeared in James Bond film A View to a Kill alongside Roger Moore.

She attended the restaurant's launch on Friday night with friend Boy George.

“The Gigi” is a take on the champagne cocktail for the fabulously rich of Mayfair, using 1990 vintage Cristal and 1888 Samalens Vieille Relique Vintage Bas Armagnac brandy.

It is topped off with “lashings” of gold leaf, Angostura Bitters and sugar.

According to the restaurant, the astronomical £8,888 price tag takes in the cost of each full bottle of alcohol, which will produce around 12 glasses worth £708 each – or about £177 per glug based on four large mouthfuls.

Cesare Papagna, the restaurant manager, said he wanted to give Jones something “truly special” to mark the occasion and combined two of his most expensive drinks.
