Where did you get the data on coffee shops and chicken shops from?
The reason I ask is that I recently purchased a house in Manchester and as part of that collected as much data as possible on things like crime stats, walking time to nearest reailway station, cycling time to work, etc. I didn't get data on coffee or chicken shops. I did consider it, and would have pulled it from OSM but that data is very incomplete with regards to this sort of data.
