OK, picture Termini station. From the station, take Via Marghera 2 blocks northeast, then hang a right on Via dei Mille. Walk almost 1 block to number 34 (I think) on the right.
The first night, I had pasta al'olio i aglio (olive oil + garlic) - simple and incredibly satisfying. The house wine: excellent. So is the arrabbiata. The tiramisu is MINDBLOWING. I don't think I will EVER have better (*sigh*).
The funny thing is that the owner and his wife are of Asian-subcontinent heritage, and the chef was of East Asian extraction. Best food we had in Rome.
