I have no experience either! This one had lots of great reviews, and I liked that it started in Campo de' Fiori, which was right around the corner from our hotel, and ended near the Pantheon. The first stop was for meats, cheeses and wine. Then we had stops for suppli (which was amazing), pizza, fried artichokes (delicious!) and ended with gelato. But the stories our guide told us as we explored just made the tour!
