Dining at a Monastery in Rome

[moosnsqrl]

A friend described a very special dining experience and we're interested to know if anyone has any information or knows if this is still possible. Here is what he could recall:

What I remember…was that it was on an island on the Tiber. I have been there twice actually. I remember it was small…with a spiral staircase on the right side of the dining room. They brought us drinking water and wine in fired clay jugs that they made. I talked them into selling me one off of our table for a buck(really). I have it at my apt here. The monks waited on us…and it seems that there were not more than eight to ten tables.  I asked my wife…she said the name of the monastery shows on the street map of Rome. My recollections are that it wasn’t very far from the Jewish section…and was on the same side of the river. I’ll keep trying…as it is not on the tourist “trail” and was one of life’s true treasures.

At first I assumed Isola Tiberina (there isn't another island on the Tiber, is there?) but later he says it was on the same side of the river as the Jewish Ghetto. There is a well known order (fatebenefratelli) who run a hospital there but I cannot find anything food-related about them, apart from their apparent use of the pommegranite as a symbol.
