An osteria is a type of Italian eatery with historical roots in hospitality, offering authentic and regional cuisine in a casual, welcoming environment. It refelcts the Italian emphasis on community, tradition, and the joy of sharing good food and wine. 

The word 'osteria' comes from the Italian word 'oste', which means 'host'. Historically, an osteria was a place where travelers could find food, drink and sometimes lodging. 

In contemporary Italy, the concept of the osteria has been both preserved and modernized. Some osterie maintain the traditional approach, offering authentic dishes in a rustic setting, while others have adapted to modern tastes and culinary trends, sometimes blending the old with the new.
