I have always been intrigued how quickly a cafe will fill up once it has a couple of people in it. You may look into a cafe and think that as there is no one in the food will be bad. once you see other people inside it gives it a sense of credibility.
I recently stopped at an ice cream kiosk on the seafront, "hows business" I asked " terrible" the little old lady inside told me. I sat on a bench with a friend eating the ice cream, suddenly she had lots of customers. People saw me eating the ice cream and perhaps the idea of an ice cream seemed attractive or was it something deeper?
is there something that draws people to a certain spot at the same time?

Some cafes can be full and turn out to be awful!! LOL...we've been taken in once or twice by full tables...we just go by the look of the place and, if we like it, we go in regardless of how many people are in it, but you might be right about attracting other people once somebody's buying something inside or even outside in your case...
