Wagamama, the David Campbell-led chain, has placed three of its London-based sites on the market as part of a continual review of its estate, M&C understands.

The company is believed to have instructed Jones Lang LaSalle to market its sites in Old Broad Street, Earl’s Court and Hampstead.

A Wagamama spokesperson told M&C: “Our plans for the current year, as previously stated, remain opening around 15 restaurants in the UK. At the same time we are continuously reviewing the performance of our entire estate, and where opportunities arise this may involve a closure – for example, the closure of Lexington Street in Soho to be replaced by a new flagship restaurant around the corner in Great Marlborough Street in Soho.”

The company, which grew turnover by 17.9% to £193.3m in the year to 26 April (FY 2014: £164m) and improved underlying EBITDA by 19.8%, resulting in an adjusted EBITDA of £30.3m, currently operates 150 sites in 15 countries worldwide.

In the UK, it plans to open around 45 new restaurants and undertake 50 refurbishments over the next three years.

Alongside UK plans, international franchise openings are being rolled out across Europe and the Middle East.
