The name osteria comes from the Latin word hospes ('someone who gives hospitality') from which the Old French words oste and ostesse derive, as well as the current Italian word oste, 'innkeeper'.

Osteria: In the past, an osteria was a place where locals gathered to play cards and drink wine. This type of establishment didn't always serve food, rather, an osteria was quite similar to a bar. Osterias have transitioned throughout the years and now they are closely tied to trattorias.

Osterias are wine bars that have evolved to serve simple meals. Traditionally, they are simpler than trattorias and usually have no menu. The offering changes daily, according to the market and two or three courses are offered for a fixed price, including wine.
