Fancy starting a food truck? It can be a way to trial new food concepts and see if your business has potential before committing to a restaurant premises.

Ruth Alexander finds out what its really like running a food truck or van. She meets customers queuing for over an hour for the SpudBros van in Preston, north-west England, where brothers Harley and Jacob Nelson have drummed up business for their jacket potatoes on social media. Ruth speaks to Anna Brand who runs a vegan food van Vege Bang Bang in Auckland New Zealand, and sisters Natalie and Samantha Mwedekeli who started Mama Rocks, a food van selling gourmet burgers in Nairobi, Kenya in 2015.

Today they have five premises and its time to sell the van that started it all. And Karan Malik talks about his food van SuperSuckers in Delhi, India. He saw the trend take off, but tells Ruth why he decided to get out of the business.
