Pre-tax profits at Mexican restaurant group Wahaca more than tripled in 2013/14, according to new accounts filed at Companies House.
The business, founded by Mark Selby and former MasterChef winner Thomasina Miers, and backed by Capricorn Ventures, recorded a £1.7m pre-tax profit in the year to 29 June 2014, up from just over £400,000 the year before.
Turnover also rose sharply, up more than 25% to £28.2m.
Founded in 2007, Wahaca now runs to 16 sites across central London and beyond, including in Brixton, Stratford and Soho, plus one site apiece in Cardiff and Bluewater, Kent.
The group also runs a "Mexican street kitchen" next to its permanent location on London's Southbank, while Miers also announced the launch of her separate, yet similar, US-Mexico-style brand DF/Mexico in London's Shoreditch in June 2014.
Alongside the wide restaurant expansion, Miers has also often spoken of her commitment to sustainable food sources, lending her name to a number of connected movement in recent years, including the Marine Stewardship Council the MSC (which certifies all Wahaca fish and is labelled on the group's menu) and the Pig Idea, a campaign to re-legalise the feeding of treated refuse to pigs, to help reduce food waste.
