THIS week’s bill from Italian restaurant Bunga Bunga was so long this column had to cut it in half. So let’s just say that ten well-funded fund managers spent £116.50 on food when they visited the Battersea venue for lunch, before frittering away seven times that amount on the more “interesting” end of the menu. Yes, that means the drinks: a gaudy list of sharing cocktails – the Colosseum, the Flaming Fiat and the Horse’s Head – with Perrier Jouet champagne, Grey Goose vodka and Martini prosecco. And, as a bonus, the restaurant provides a definitive translation for “bunga bunga” – it means, apparently: “Can I show you the private room upstairs?” Berlusconi would approve.
