The entrance to the Wood Street Market is very Wes Anderson like so I couldn’t resist and took a picture of it. 
If you ever visit Walthamstow I recommend you visit this place. It’s in the Wood Street area. This little market is full of shops where you can find everything from bikes to vintage clocks and antique toys. And for you vinyl lover, there is a shop right by the entrance where they sell second hand vinyls at really good prices. 
Also, if you feel hungry, visit Homies on Donkeys right inside the market, the best tacos in London!
