There is a place in Trastevere right off of Via Trastevere on via San Francisco a Ripa (sp?). It should be across from a Pasticceria/Gelateria and it was fantastic, though 4 years ago. Door should be black.. Sorry I can't come up with much else, most of my best dining experiences in Rome and Italy have been wandering around and just stumbling into places (try to make sure that the menu is not multi-lingual.
