This is hands down the best icecream sandwich I have had, regardless that it's vegan. I had the ginger ninja cookies with the vanilla icecream and it was perfection! The cookies were soft, chewy and crisp all at the same time and held their shape.
It was extremely difficult to find though, but well worth the adventure. Enter near the sign on the bridge saying "Camden lock" and it's near all the food stores, underneath the pub.
