It's always a treat to have some home-style meals in Rome. Sometimes Americans have difficulty reading the menu, though.
One little booklet that I highly recommend and enjoy is entitled The Marling Menu-Master for Italy by William E. and Clare F. Marling. It's a delight to read.
Being a tour guide, too, I like to recommend, although it goes without saying, the French custom when traveling, of drinking the "vin du pays," the local wine. Enjoy!
