Kate Middleton takes home dog biscuits for Lupo after trip to Fortnum & Mason with Queen and Camilla
The Duchess of Cambridge, 30, who was accompanying the Queen and Camilla, Duchess of Cornwall, sampled a crystallised rose petal, which staff at the shop said would be even nicer dropped in a glass of champagne.
'Oh yes, I will definitely try that. Gosh, it is very sweet,' Kate said.
Kate - who wore an above-the-knee blue Missoni coat with grey heels and a St David's Day daffodil brooch for the event - was also given dog biscuits for her and Prince William's black cocker spaniel Lupo.
Along with the Queen, 85, and Camilla, 64, the Duchess unveiled a plaque in the store, which marks Piccadilly's regeneration.
