Esteemed author Charles Dickens frequented The Grapes and honoured it by including the venue in his novel, Our Mutual Friend.

The research by Wealth of Geeks provides a closer look at the different side hustles taken up by celebrated personalities in Britain.

Other top side hustles included Charlotte Church's retreat, The Dreaming in Wales, and Hakim Ziyech's Taco Taco.

A spokesperson for Wealth of Geeks said: "Establishments owned by celebrities as a side hustle has emerged as a prominent trend in the hospitality industry, and it's interesting to see what the public thinks are the best-rated.

"The range of celebrities who have ventured into the hospitality sector varies from football legends to musicians and actors, which demonstrates how attractive it is as a business opportunity.

"However it’s also a risk, because poor reviews from customers could do more than just impact people’s opinion of the establishment, they could also damage the celebrity’s brand and persona.

"Therefore the celebrities who feature at the top of this list will be pleased their side hustles are proving popular with the public."
