Chain reaction

I wouldn't wish norovirus on my worst enemy - well, Donald Trump, Paul Dacre, Katie Hopkins and Jamiroquai, perhaps - and so certainly not on a chain of Mexican restaurants whose colourful, tasty and reasonably priced food has always served me well on visits to London, most recently in Kentish Town in August. I wouldn't fancy being the person responsible for Wahaca's PR at the moment - but here's hoping they can get themselves back on their feet and recover their reputation before too long.
