It came as London hospitality bosses said they are seeing huge numbers of reservations for the weeks following April 12 – the date the Prime Minster has pencilled for the re-opening of al fresco dining and beer gardens.
Des Gunewardena, boss of fine dining group D&D London, which is behind London institutions including Quaglino’s and the Bluebird cafes, labelled the level of forward bookings the group is seeing as “extraordinary” – with around 50,000 reservations already taken.
He said: “Our bookings are double the level of bookings we had on the first day of reopening after lockdown last July, and we are still a full month ahead of reopening.”
Charlie Gilkes, co-founder of the Inception Group – which counts Bunga Bunga, Mr Fogg’s and Cahoots among its roster – said that there is “clearly huge pent up consumer demand”.
“Bookings have been really busy, it’s really encouraging so far,” he said. “We wish we had more outside space and now just hope April showers aren’t on the way.”
Sam Harrison, founder of Hammersmith restaurant and waterside terrace, Sam’s Riverside, said that within a few hours of opening booking lines last Thursday the site had “over 2000 bookings – and that has continued”.
Kate Nicholls, chief executive of UK Hospitality, has warned that April is “not a reopening at all, for much of the sector”, however.
She said: “We need to remember that nearly 60% of hospitality businesses don’t have outdoor areas and many that do only have small spaces.”
From May 17, restaurants will be allowed to offer indoor seating to diners from two households or groups of up to six people.
