Simon King is to stand down as managing director of Burger & Lobster to oversee the growth of Shake Shack across the Middle East, Turkey, Russia and the UK, MCA understands.

King is to leave the Goodman-owned Burger & Lobster chain in September to become a vice president of international franchise operator Alshaya.

He joined Burger & Lobster in April 2014 after 27 years with Mitchells & Butlers (M&B). He leaves Burger & Lobster as it enters a period of consolidation.

It is understood that the company will continue without a managing director for the time being as it looks to consolidate its operation in the UK, with the group understood to be struggling to replicate its successful formula in the regions.

Earlier this month, the company, which operates 13 sites in the UK and four overseas, ended its “no-menu” policy after receiving over 1,000 emails asking what it serves.

It also recently launched a new lower-priced “entry-level” menu at its Cardiff site, which if successful could be expanded to its other regional units in Bath and Manchester.

The change comes as the company looks to further enhance its international estate, with the group on-site in Malaysia on a new restaurant with the Genting Group and a site in Jeddah, Saudi Arabia set to open later this summer. It will open a second site in New York later this year.
