In Italian, impersonal statements are formed by using the pronoun si followed by the third-person singular form of the verb. This is similar to impersonal statements in English that are preceded by the subjects “one,” “they,” or “people.” In Italian, the impersonal subject is implied because the sentence does not have a direct object.

Si mangia bene in quel ristorante.

One eats well in that restaurant.

If the sentence contains a singular direct object, Italian uses the pronoun si followed by the third-person singular form of the verb. When the sentence has a plural direct object, si is followed by the third person plural form of the verb. This construction implies the passive voice.
