I think this is the absolute best coffee place in Rome and go often. Anytime of day that you are in this area stop for an espresso. Go in and turn to the right and order an “espresso with sugar to go”, from the girl behind the register. Pay for it, then get your receipt and go across the room to the counter and hand your receipt to the barista. Take your coffee outside and enjoy. Return the cup and be on your way. It’s like a 3 min stop and I never skip it.
