Laura Reynolds for the Londonist:
Being largely made from milk, ice cream presents quite a stumbling block for vegan and dairy-free diners looking for a quick summer cool-me-down. In recent years, vegan ice cream has become more common and more tasty, and much more readily-available, as per the below London cafes and restaurants which all serve dairy-free versions.
Good selection of where to find plant-based ice-cream in London. Shame I don't live there anymore :)
