well this will be tricky as I seem to have mislaid my notes. So the images might not relate to the cafe.
One thing I can tell you though is that they all have good coffee.
Check opening times as some are Monday to Friday. There are more, so hopefully I can track down my pictures to add to this entry.
I have also added a link to coffee tips from a local London newspaper at the bottom
