The Real Greek is to open its new London restaurant, on Soho's Berwick Street, on 4 March.
It will be the brand's seventh London site and its eighth in the UK.
The new 1,716 sq ft restaurant will accommodate 75 covers and sits adjacent to Oxford Street.
It will be run by general manager Kostas Kyriakou who previously ran the group's restaurant in Covent Garden.
The Real Greek serves hot and cold Mediterranean meze dishes, with many ingredients such as the wine and olive oil imported directly from Greece.
"Since the launch of the first The Real Greek in 1999, we have noticed there's a real appetite for Eastern Mediterranean food, which is healthy and nutritious, and we have opened and continue to open our restaurants to accommodate this growing demand."
