Alan Yau’s casual-dining Thai chain Busaba Eathai is seeking a new managing director, after Jale Erentok stepped down from the role she has held for the last two years.

Erentok, who is Yau’s wife, is believed to have left the company, which she joined in 1999 as operations director, at the end of last year. She is thought to be aiding her husband with a number of his new upcoming projects including Duck & Rice in Soho and an unnamed venture in Shaftesbury Avenue.

Previous to joining Busaba, which is Phoenix Capital Partners, she was operations director at Hakkasan Group for seven years.

Earlier this year, Busaba announced plans to double its estate over the next three years, with two more London openings in 2014 and an extra focus being placed on further expansion outside of the capital.

The group, which currently has nine restaurants in London and one in Oxfordshire - will open in Shoreditch and Kingston in the summer and actively looking for sites in Manchester, Liverpool, Leeds and Bristol.

It is also thought to be close to securing an opening at the O2 Arena.

It launched its very first bar within its Old Street site last week.
