William and Kate partied with their close friends, including Prince George's godmother Emilia Jardine-Paterson d'Erlanger, at the playful first floor venue which is known as an "Englishman's Italian" and has a pizzeria and karaoke room.
Italian-themed posters, newspaper articles, maps, tourist brochures decorate the kitsch bar, where sensational bruschettas and metre-long pizzas are served on a board.

SuperMario Monti and Berlusconi Bellini are just a couple of the tipples from the creative cocktail menu which promise to complete a fun-had night.
Meanwhile, William's younger brother Prince Harry whisked girlfriend Cressida Bonas to exclusive celebrity-favourite The Ivy, situated in the heart of the capital's West End.

The couple were joined by Cressida's brother-in-law Sam Branson at the famous A-list haunt, where the likes of the Beckhams, Kate Moss Jude Law, Tom Cruise, Elton John and supermodel Elle Macpherson all dine.
The Ivy serve traditional British dishes in cosy surroundings with lashings of style and sophistication. The surprisingly down-to-earth menu offers traditional dishes from dressed crab and shepherd’s pie to steak and the market fish of the day.
