Sundays on Portobello Road are a lot less hectic and people packed than Saturdays. The market is closed, but there are still plenty of interesting shops selling antique goods and vintage treasures, cocooned by the famously colourful walls.
Although there aren't many street food vendors out on a Sunday, there are plenty of good places to eat and drink in the area (we popped into Honest Burgers, a review will be up shortly!), as well as tempting crêpe stands and the ever popular Hummingbird Bakery.
If you're visiting London or are in the area (particularly on a sunny day, as with all places), it's a must-see spot and great for street photography.
