The term osteria is Italian and was historically used to define a place where wine was sold. Some osterias would serve light meals or allow you to bring your own food. But, traditionally, most osterias only sold wine and may be considered equivalent to a wine bar today.

noun. [ feminine ] /oste'ria/ (locale) inn , pub , tavern.

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'.

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.
