This in itself is an interesting shift. The original food trucks were intended to bring hot food to areas of the city that lacked it, feeding the hungry workforces there and sometimes starting in the early hours of the morning to supply the construction crews heading to work, or late at night after nightshift workers had finished up and restaurants were shut. Long gone are the days when street food meant only grease and convenience. Now it equals fresh, often local, ingredients and extremely varied international offerings, all served up hot and delicious by some of the most passionate foodies in London.
