Little Italy is the catch-all name for an ethnic enclave populated primarily by Italians or people of Italian ancestry, usually in an urban neighborhood. The concept of "Little Italy" holds many different aspects of the Italian culture. There are shops selling Italian goods as well as Italian restaurants lining the streets. A "Little Italy" strives essentially to have a version of the country of Italy placed in the middle of a large non-Italian city.
