The easiest way to taste genuine Italian food in an original way, without to seat in a traditional restaurant, is to go to Eataly. It is a big recent store where you can both to buy and to eat high quality Italian food and drink. So you can directly taste some food there and if you like it you can buy a sample to take home for your family and friends. I suggest this solution if you have an hour to spend in a store at the lunch time. Near Eataly you can visit the famous National Automobile Museum of Turin, at just 5 minutes walking from there.
