More for interest than anything else
Whilst watching my 'streaming box' (ooo erh matron) in the kitchen the other night, I get the local news update from London instead of north eaast and there was a report about food hygine inspections by Which magazine and Lewisham was ranked 396th out of 398 worst hygenic food businesses in the country. Heres a map from Which magazine
http://consumerinsight.which.co.uk/maps/hygieneThe report also stated that you can go on the Food Standards Agency site and look at results for all of Britain.
A bit further investigation by me found a smart phone app called Scores on the Doors
http://www.scoresonthedoors.org.uk/which tells you the ratings around where you are. It certainly makes interesting reading.
I'll save my opinions for later.

NB. Just looked more closely at the map and Edinburgh (which was my second home for most of my school life) is worse than Lewisham.

Enfield is the worst
