At this stage of the route you will be worn out! You can have a plate of pasta near Piazza Navona to recharge your batteries. Our choice is the Mimi e Coco restaurant (Via del Governo Vecchio 72). If there are a lot of people, the service might be a little slow, but take it easy and enjoy the rest. The food is good and the location is great, near the Piazza Navona, but not right there, so it's less turistic.
