Resurrecting a very old thread, but seeing as this chicken shop (Maxin Grove Vale) is popular with kids, I wanted to warn people that the kitchen staff are literally sharpening their knives on the public pavement on Derwent Grove. I can hear an alarming metal sound outside daily - I look out and there's a guy wielding a 7 inch knife and scraping it along the floor. Needless to say, London's streets carry all sorts of dirt and, not trying to be melodramatic, disease - there's a fox that likes to hang out DG so god knows what sort of illness you could contract due to this practice. AVOID AVOID AVOID.
