We had a wonderful dining experience at the Da Fortunato. The food was exemplary. The wait staff were friendly -- the usual Italian hospitality.
We had local dishes e.g. pasta, salad, calamari and tiramisu for dessert. Great food and ambiance. We noticed that people who frequent this restaurant are all well-dressed, most of them are.
Be sure to dine al fresco for a nice view of the Pantheon.
