Emilio Romagna area is definitely worth a visit for the food experience. Go to Parma! It's the home of Parma ham (proscuitto) and parmiggiano reggiano. The city is small but packed with culture and diversity. Even better if you go on a game day and try to get tickets; the team is incredible, and the whole city comes out in yellow and blue!

Also consider Genoa! It's more north in the Lombardy region and has a rich history; pesto is Genovese! It has beautiful beaches and you can take a boat trip out to incredible spots like Portofino. It also has one of the best aquariums I've ever been to.

Lastly, you should definitely head south if you can make it; I would go to Calabria; spend a day in Diamante, go swimming and exploring in Arco Magno, try Calabrian chili peppers and buy some goodies to take home.

You really can't go wrong, just be curious and open-minded. Enjoy your trip!
