Forget posh, Michelin-star restaurants. Some of the best food around is now being served at affordable prices from pop-up cafes and restored trailers. What we are seeing is a grassroots revolution in British food whose most eminent champion is Richard Johnson. He tells the remarkable stories of the budding entrepreneurs who have chosen wheels over bricks-and-mortar to peddle their wares. From the porridge bar outside Edinburgh castle to the coffee cart on the north coast of Ireland to the banh mi stall in London's East End, these vendors serve up delicious meals that are prepared and cooked right in front of you. The mobilers' stories form the backbone of the book, which is peppered with 60 inspiring recipes from around the world.
