The group has signed on a unit in the £400m Islington Square retail, leisure and residential development, which will launch in phases from the end of October.
It will be the first north London site for Megan’s, which launched on Chelsea’s King’s Road in 2002 and now has restaurants in Clapham, Battersea, Fulham, Parsons Green and Wimbledon.
Megan’s is known for its dog-friendly sites, all-day brunch and Mediterranean-inspired evening menu.
Islington Square is located on the former site of the Royal Mail sorting office and has been developed by real estate investment firm Cain International.
CBRE has been appointed to act as asset and property manager.
