What is the origin of many "Ray's Pizza" stores in Manhattan?

The origin of many "Ray's Pizza" stores in Manhattan can be traced back to Italian immigrants. These immigrants brought their culinary traditions, including pizza-making techniques, to the United States in the late 19th and early 20th centuries. They established pizzerias that became central to the fabric of New York City's food culture. The style of pizza that Ray's and similar establishments offer reflects the Italian heritage, having developed over generations within the city.

In contrast, other options such as refugees from Albania, local New Yorkers, or tourists do not align with the historical context of how iconic pizza shops like Ray's were founded. Italian immigrants laid the groundwork for the popularity of pizza in New York City, making their influence pivotal in the establishment of numerous pizzerias throughout Manhattan.
