The group has secured a 110-cover site in Wimbledon village, with plans to develop a further 75-100 covers upstairs over the next two years.
“We see Brexit as having burst the London bubble a bit and as prices fall, we’ll be looking to capitalise on our strong financial position,” says Andy Laurillard, co-founder of Giggling Squid.
“The plan is to dramatically expand into the Greater London area over the next few years.”
The group is currently in negotiations to acquire several further properties within the M25 ahead of the launch of its 20th site, in Farnham, in April.
Giggling Squid was founded by Thai-born Pranee Laurillard and her husband Andrew in Hove in 2009.
In 2015 the group received a £6.4m investment from the Business Growth Fund, followed by an £8m bank facility from Barclays, to accelerate its expansion.
Further restaurants are also set to open in Brentwood and Windsor this summer.
