queuing since it was founded and is aiming to seat 2.5 million people by the end of the year.
Most notable though is how much money is says it has saved restaurants: on average users have seen their takings rise by 15 percent a night on average since adopting the app.
Speaking to The Evening Standard, co-founder and CEO at WalkIn, Amos Teshuva, said:"Bookings constantly fail to show up, which means busy restaurants have had to make people wait in line to avoid empty tables. Not because the restaurant wants to, but because they have had to."
"WalkIn is changing that by giving restaurants and diners all the benefits of bookings with none of the drawbacks of no-shows. We want to get to a place where people no longer have to spend hours waiting outside a restaurant getting bored and tired."
The Breakfast Club, Flat Iron, Kricket, Pastaio, Din Tai Fung and Pizza Pilgrims are a handful of the 40 London restaurants that have started working with the company so far.
The Breakfast Club co-founder Jonathan Arana-Morton said that the impact of using the app was immediate.
"Sales have increased, customers are much happier and our staff bought in - win win."
There is of course the drawback that the app is only available to London restaurants, not to mention that it is only likely to be useful to busy restaurants - not providing a solution to those who suffer the most from no-shows.
What do you think chefs? Would this work at your restaurant? Do you think could help curb the impact of no-shows?
