This migration gave birth to a cultural boom in cities such as Chicago and New York. In Chicago for instance, the neighborhood of Bronzeville became known as the "Black Metropolis". From 1924 to 1929, the "Black Metropolis" was at the peak of its golden years. Many of the community's entrepreneurs were black during this period. "The foundation of the first African American YMCA took place in Bronzeville, and worked to help incoming migrants find jobs in the city of Chicago." The "Black Belt" geographical and racial isolation of this community, bordered to the north and east by whites, and to the south and west by industrial sites and ethnic immigrant neighborhoods, made it a site for the study of the development of an urban black community. For urbanized people, eating proper foods in a sanitary, civilized setting such as the home or a restaurant was a social ritual that indicated one's level of respectability. The people native to Chicago had pride in the high level of integration in Chicago restaurants, which they attributed to their unassailable manners and refined tastes.
