You are getting some good information here but have you considered what your proposition will do to the owner's business? Are you going to be taking away customers? If so, he may be asking you for quite a bit of your profit to compensate him for the loss.
Have you thought about a food trailer? It has more flexibility than a fixed location especially if you are trying to do this on a small scale.
