This is not related only to Emilia-Romagna, but could be helpful for several people, because one of the main Emilian attraction is the food.
The 4th of August will be the Italian Food White Night. There will be several happening, show cooking and shows in several cities. In Emilia-Romagna I believe everywhere. If you are here in that period look for what will be available.
Why 4th of August? Because is the day when Pellegrino Artusi born 198 years ago. If you don't know Artusi you are not Italian foodies!
Here an article (in Italian) with the official presentation of the event: ansa.it/canale_terraegusto/notizie/istituzio…
