This is definitely a must in London (at least for all flower lovers :-))...Columbia Road Flower Market on a Sunday morning - a wonderful color palette, a lot of people and the never-abading shouts of the flower vendors "five for a fiver"...
Get some good coffee and a croissant from the French bakery stand on your way up Brick Lane and then enjoy all the colors and scents while floating through the crowds on Columbia Road!
Don't miss the little boutique on the right-hand side at the end of Columbia road - everything whimsical and handmade, better leave the guys outside :-)
They have little mystery packs - a great surprise for the big child in me :-)
I got a little sewing kit which came in very handy during my time here in London!
