Yes I noticed the same thing last week @ a wing stop. People would walk up to the door even put their hand on the knob then just as suddenly when noticing no one was inside walk away to a busy subway next door. But have you ever tried the food @ one of these unbusy places? Well if you did then you would know why they are not busy. When people find good food they will talk about it later and that will drive business to that business. Word of mouth is still the best advertising out there in my opinion.
