Pho, the Isis Equity Partners-backed Vietnamese fast-casual concept led by Stephen and Juliette Wall, is set to strengthen its London presence in the first quarter of next year after exchanging on a further two sites in the capital, M&C Report understands.

The nine-strong group, which opened in Leeds in October, has exchanged on sites in Chiswick and Battersea Rise as part of plans to open five restaurants in total in 2014.

The company has already secured a further site at Birmingham’s Grand Central shopping centre for an opening in 2015.

In September, Stephen Wall told M&C Report the company has had a “robust year to date with very strong trade at our high street sites in particular compensating for the heat wave knocking sales a little at our two Westfield-based sites”.

The group, which is chaired by ex-Wagamama chief executive Steve Hill, hopes to grow its estate to up to 25 sites over the next three years.

Insight Retail acted for Pho. Dean Gambles & Co acted on the Chiswick deal.
