Moore's situation is not an isolated one, with staff shortages being reported across the industry.
This month, Michel Roux Jr also said he was being forced to cancel lunch service at Mayfair's two-Michelin-starred Le Gavroche opting to serve dinner only, due to staff shortages.
Announcing the news in an Instagram post the chefs said: "Since opening, restaurants up and down the country have suffered greatly with staffing problems partly due to new Brexit regulations as well as there now being a major lack of well-trained hospitality professionals since the pandemic struck."
Mauro Sanna, the owner of Olivo, a Sardinian restaurant in Belgravia, has also been forced to close his restaurant for lunch on Saturdays and all day on Sundays because of too few workers, particularly chefs, reports the New York Times.
Sanna said: “I knew that there was going to be a problem with Brexit, but I didn’t think it was going to be such a hard landing.” Having failed to get any applicants at all from an advert posted in Sardinia, he's now offering his staff £100 to find someone they can hire.
Across the hospitality industry, there are about 188,000 open positions, reports Kate Nicholls, the chief executive of UKHospitality.
As restaurateurs call for the government to grant work visas for people wanting to work in hospitality in the UK, and calls by critics like Jay Rayner for customers to pay more for the privilege of eating out, it remains to be seen what the future holds for an already vulnerable industry.
