From a different point of view, take a step back and look at your brick and mortar as more of an anchor. It restricts you to that particular location, and clientele. Going mobile, whether it’s cart or perhaps a mobile type canteen or kitchen will give you the flexibility of moving your investment to different locations. I believe this is why the food truck phenomena is bringing in some of the bigger players. They run the numbers on expanding to permanent locations, versus portable ones, and the risks are definitely less, especially in marginal areas. Make sure you have the foot traffic and product variations to support a permanent location if your only experience is a simple street food type product.
