The brand has secured a former NatWest Bank building in Lytham, Lancashire for its upcoming 110-cover restaurant this autumn.
Founder Dean Wilson opened the first Olive Tree Brasserie in St Annes in 2008 aged just 22, before expanding to Stockton Heath, Chester and Preston.
“We’ve been waiting for the right site to come along for us to set up in Lytham and we’ve beaten stiff competition from some fantastic restaurant groups to secure this spot,” says Wilson.
The new restaurant will feature a central copper bar, private dining room and function space.
It is expected to create 30 jobs for the local area.
Wilson told BigHospitality last year that Olive Tree Brasserie had began working with a Greek recruitment agency after struggling to hire UK chefs.
The group has also begun putting more emphasis on apprenticeships and retaining and developing existing staff due to the uncertainty around immigration following Brexit.
