SBC did decide to remove all temporary food stalls in the Town Centre, under the guise of improving the look - that clearly hasn't worked so well based on my visit in the summer. I think they were looking at that but probably only event related. So, it is likely this is not in a prime location. Having been over here for a while, it's interesting to see the food truck approach - not seen like the dodgy kebab van on the side of a busy road, but more setting up stall around busy business districts and getting the white collar dollar.
Speaking to temporary food stalls. I used to love the baguette van between phones 4 u and next (i think) near the bible book shop.
