I went there yesterday with my hubby and we both though this place was very authentic.
First off, the old lady which is likely the owner speaks some English, but definitely Italian. The staff speak Italian together and they seem to be family.
We ordered the arancini for starter and then the dominico pizza as a main. They were both very good and fit well with the Sangiovese red wine we ordered.
The place is pretty small and the decor is modest, it's quiet so I would recommend it for couples or small groups.
