Food for Thought.

I began to think about the second half of my data and how it differs slightly from the criteria of my first. By this I mean that the fact that all of the restaurants from which I collected from in the French Quarter were located almost right next door to each other, and in Metairie and Kenner, this is not the case. The restaurants in these areas are located blocks away, sometimes with three or four streets in between. I am starting to wonder if this will have a profound effect on my data--possibly adding in some sort of bias into my results. Does anyone have any suggestions or comments on this issue? In the end I guess it might just be true when people say, "Location is everything."
