Darius Namdar is the fast rising star in hospitality, and a snappily dressed one at that. Having left a career in finance, his first prominent role was at The Wolseley in Piccadilly as maître d'.

Once he'd oiled that particular machine, he is now stationed as Club Director at the refurbished Marks Club, the newest wrinkle in the capital's social scene. Spot the pattern?
