How much money to have lunch in Italy?
It depends a lot on whether or not you’re going to be in a tourist city or smaller towns, and on how cheap you’re willing to be. I lived in Trento, TN for three months and found that when I went out, I could expect to spend between 4 and 6 euro pretty regularly (if I bought, say, some pizza and a soda). If I went to a bread store or a grocery store and bought the ingredients for my lunch there, I could easily spend less (or easily spend more). 5 euro a day is probably a reasonable estimate. If you’re going to more touristy cities, I suggest asking where there’re cheaper places wherever you’re staying. When I stayed in hostels in Milan and Venice, the hostel clerks were able to direct me to less expensive–and tasty!–places that still had a little local flavor.
