When I lived in NJ near the Tappan Zee Bridge, I went to a fireworks display in some town/city on the Hudson that had a long history of waves of immigrants displacing prior waves, and then being displaced in turn. Haverstraw?
I sat next to an older guy who had lived there all his and seen them come and go: Italians, Irish, Portugese, Haitians, Puerto Ricans and several other ethnicities I forget now.
He said that every group that moved in, always brought their own bakeries, because bread is so basic, and every culture has their own way of making it.
When each group moved up and out, most of "their" bakeries closed but, he said, ONE of each nationality always stayed open, because enough people found they really liked THAT kind of bread.
Also, for 1-2 generations, people would drive for miles from the suburbs to come back for "their kind" of bread.
As a result, the town's bakeries were like a history of immigration patterns, a United Nations of bread.
