Little Italy, being an Italian enclave, has a heavy presence of the Italian Mafia. It gives the impression of being an "old-world", working-class neighborhood with its cobbled, narrow streets. As with many of the older, old immigrant-heavy neighborhoods in the city, the neighborhood features a number of pre-war style tenements, with many alleyways intersecting the short city blocks. Most of the neighborhood's aforementioned restaurants are clustered along Brown Place, where as Denver Avenue serves as the main commercial strip.
