The Prince and Princess of Wales stunned royal fans as they jumped on the Elizabeth line to enjoy a pint in a Soho pub on Thursday.
Ahead of the Coronation weekend, Kate, 40, and William, 41, boarded the Lizzie line at Acton heading towards Tottenham Court Road.
While on the Tube, the pair spoke to Transport for London workers about how they’re preparing for the busy weekend.
The couple then exited via Dean Street where they walked to the Dog and Duck pub in Soho to enjoy a pint with locals.
Kate and William then delighted onlookers as they spoke to members of the public in the area just two days ahead of the Coronation.
On Wednesday, William and Kate joined the King, 74, and the Queen Consort, 75, for a rehearsal at Westminster Abbey.
The Royal Family was greeted by the Dean of Westminster and shown inside the gothic church, where Charles and Camilla will be anointed and crowned on Saturday in front of 2,300 guests and a global audience of millions.
Future monarch George, 9, has the duty of being one of his grandfather’s pages of honour and is expected to be tasked with holding the train of Charles’s regal robes.
William will kneel before his father and vow to be his "liege man of life and limb" in the only homage of royal blood of the ceremony.
He will also help clothe the King in his golden robe royal, also known as the mantle, ahead of his crowning.
While the royals put the final touches to their preparations, fans have already set up camp along The Mall in order to catch a glimpse of Charles and Camilla.
John Loughrey, 68, claimed to be the first person to set up his tent on the Mall on April 27, nine days before the Coronation.
He told the PA news agency: “We like the build up, the rehearsals and seeing people throughout the day.
“There are a lot of tourists and they come and say they wish they had something like this in their country.”
