Half way down White Cross Street, near Old Street, you will find an old Venetian blind, carefully woven between some railings, to create a private corner.  It is very subtle. 
On Friday lunch time between 12-3pm,  White Cross Street is a bustling market with food and the Fordham Gallery Stall. 
Fordham shows a different artist every two weeks. It gives you food for thought and you can meet the artists and all their friends.
