Locket’s is a new café from the owners of Wiltons in Jermyn Street. Wiltons is the restaurant that dukes visit when they have fallen out with White’s. It has a sign featuring a lobster that looks like Benjamin Disraeli wearing a top hat. When a bomb fell nearby in 1942, its anxious owner immediately sold it to the banker Olaf Hambro, who was sitting at the bar, by adding the price of the restaurant to his bill.
