This review is especially helpful for those who have or use the following: Powerchair
Fun place to visit if you like good food. The layout makes it possible to easily explore all of the stalls. The road surfaces are bumpy so it does depend how much you can tolerate but it's no worse than most inner city roads.
Transport & Parking
There are disabled parking spaces in jubilee street and park street just outside the market. We found one without any problem. I haven't tried london buses or the tube in my wheelchair but both stop nearby.
The stalls are accessible and a great height for wheelchair which made it a very enjoyable place to visit.
They have a good, big toilet with grab rails but filthy and smelly.
