Paris
For about a century, there's been a restaurant here in this weathered stone building erected about 600 years ago in Trastevere. Over the years, this cramped but convivial place has turned out thousands of platters of authentic Roman cuisine, usually with an emphasis on seafood. This is old-fashioned cooking; don't look for the latest foodie trends. Despite that, you're likely to be very happy here, thanks to heaping portions of dishes

Myosotis
Midway between Piazza Navona, the Pantheon, and the Italian Parliament, the building that contains Myosotis is relatively modern and nondescript, but as the name promises (translated from Latin, it means "forget-me-not"), you're likely to remember the food for a long time.

Abruzzi
The good food and reasonable prices make it a big draw for students. The chef offers a satisfying assortment of cold antipasti. With your starter, we suggest a liter of garnet-red wine. If you'd like soup as well, you'll find a good stracciatella. No one in Italy does roast lamb better than the Romans, and the selection here is good
