Food trailers have been popular in urban areas for a number of years, and when they became well known, some of them transitioned into traditional retail locations.

Once you are convinced that you have a product people want, phase 2 is to find the right brick and mortar location.
You do that by identifying 3 or 4 locations where you think it would work, and park the trailer in front of each for a week or 2.
Then run the numbers. How many people in that location risked changing their eating habits? How many came back? How many brought friend? All these factors play into reducing risk…
The best part is, while you are building out the restaurant, you can continue to run the trailer in the location building a customer base and getting people excited about the pending opening…
