Prince Charles was not with his wife, son and stepchildren, The Daily Mail reported. William and Camilla, Duchess of Cornwall, are rarely seen together in public and the prince is spotted more often with his younger brother Prince Harry, than with his stepsiblings, Tom and Laura Parker-Bowles.
The foursome ate in Scott's, a fashionable Mayfair restaurant on Friday. William's uncle, Prince Andrew the Duke of York, his ex-wife, Sarah Ferguson, and their two daughters, Beatrice and Eugenie, were dining in nearby Cipriani's at the same time, accompanied by Princess Beatrice's boyfriend.
His dinner with the duchess was an unusually sober evening for William. On Wednesday, a party that included princes William and Harry, William's girlfriend, Kate Middleton, and other friends spent $30,000 at the nightclub Boujis, mostly on premium champagne.
