I will be in Rome in April. I've booked Gatta Mangiona. tel 06 5346702 for pizza, La Matricianella. tel. 06 6832100 for traditional and La Pergola at the Hilton for high end. Have not been to Rome for over 10 years so these are based on what I have found here at Chowhound and on other internet sites. Any comments from others on these choices.
