Italy's currency is euro.

If you have a Visa you don’t need to take large sums in cash or traveller’s checks: There are cash dispensers everywhere, and you’ll always find one with the banner "Cartasi," affiliated with Visa.
Attention, the network Bancomat doesn’t allow the withdrawal by Visa. Diner and American Express are accepted in most hotels and restaurants. Excluding gasoline and suites hotel, the cost of living, as well, is lower than that in France. "A quality equal" is of course subjective, but, for example, you’ll never eat mediocre in a restaurant, down to 15 euros.

An expensive meal in a nice frame, it costs 15 euros. A very expensive meal in a luxurious place, 30 euros.
