Mexican restaurant operator Tortilla is to open another seven sites, with the first four to be launched before the end of this year.
A further two sites are due to open early next year, with the final site opening before October 2014.
The new openings are located both in and outside London and include: Land Securities' Trinity Kitchen development, Richmond directly across from the station, Birmingham's Grand Central shopping centre, and in Clapham.
The additional sites will bring the total number of operating restaurants to 18. The company is also in advanced legals on three more sites which are expected to be confirmed over the coming days. Even before these openings, Tortilla already claims to be the UK's largest fast-casual Mexican restaurant operator.
The restaurants serve classic Mexican dishes including burritos and tacos with a range of fillings and toppings such as carnitas, barbacoa, grilled chicken and grilled steak.
Founder and MD Brandon Stephens said he was "very pleased with the strong store performance and pipeline that the team have generated".
Tortilla has seen significant growth in the past year, with EBITDA up 75.9% and sales growth up 76.5% on 2011 numbers.
