I'm often asked which was my favorite city, Paris or Rome, and my answer is always Paris for the sights and Rome for the food. When in Rome dine at Pizzeria "Ai Marmi." This restaurant came recommended to us from all different directions. It's located in Trastevere on the Tiber River.
Surprisingly, it has delicious pizza (and bruschetta).
Speaking of bruschetta, I recently learned it is pronounced 'broo-sket-ah' not 'broo-shet-uh'... I had no idea! It's never, ever too late to learn something new.
