Here's a link to the web site of a church that my family and I visit when we are in Rome...

Interestingly, they have some decent information about restaurants and recommendations that you can drill down to from "Visitor Information" on the Home Page... I have eaten at a number of the restaurants recommended and am particularly fond of the GIRARROSTO TOSCANO at Via Campania 29 near the Villa Borghese and the ALLA RAMPA at Piazza Mignanelli 18 near the Spanish Steps...
