Caffé Sant’Eustacchio
Piazza di Sant’Eustacchio 82, 00186, Roma
The best coffee you can have is at Caffé Sant’Eustacchio, often full of people but they are quick in serving, it is near Piazza Navona and Pantheon which are both must-sees for newcomers to the city, so you’ll easily find yourself in the area.
Giolitti
via degli Uffici del Vicario 40, 00186, Roma
The best ice-cream can be found, without a doubt, at Giolitti. The cue here often scares people away, but don’t be, sit at a table rather than taking the ice cream to go and it will be a nice stop to rest after having walked throughout the day. Giolitti is in the city center, not far from Caffé Sant’Eustacchio, so you will find yourself in the area quite easily.
Babington’s Tea House
Piazza di Spagna 23, 00187, Roma
Right to the side of the famous steps of Piazza di Spagna. Please beware the prices here are hefty but I recommend you stop by even if you are not planning to eat or drink anything as it is a very interesting place to see, so do have a walk inside.
Romolo alla Mole Adriana
Vicolo del Campanile 20, 00139, Roma
If you are visiting the Vatican and you are looking for typical Roman dishes, this is a great place where to stop, not far from Basilica di San Pietro.
Osteria delle Commari
Via Santamaura, 33-5, 00192 Roma RM
This place is 300m from the Vatican Museum, it is a great place where to have a bite to eat either before or after your visit. Again, this is a very typical place where to have traditional Roman dishes.

Osteria Barberini is 10min away from Piazza di Spagna (walking), so right in the city center. It is a great place to stop and eat if you are taking the tour of the center and stopping at Piazza di Spangna.
Amedeo Ristorante
Via Principe Amedeo, 16, 00185 Roma RM
This restaurant is close to the Roma Termini train station, which makes it a great place where to go and eat before catching the train to another destination. The food, again, is typical from Rome and the service is fast.
