Great Bites in Rome

We have some friends who are heading to Rome in the next few months and they'd asked for various recommendations, including where to eat while in Rome. Here are three restaurants that I recommended (and one that just came to mind):

Da Giggetto - This is a Roman institution, located in the old Jewish ghetto in the shadow of the portico D'Ottavia. Great Roman food with some emphasis on Jewish specialities like artichokes. The cacio e pepe is delicious.

La Taverna Degli Amici - I've eaten here over the years... on business trips and during our honeymoon. It's a terribly romantic location - tucked into a small little piazza on the edge of the Jewish ghetto, right next to an old medieval tower. If you can, try to score an outside table. - it may have changed names but it's the same location. A romantic spot.

La Cicala e la Formica - A cute little restaurant located in the Monti area of Rome. Seating is somewhat limited but the food is excellent. Check the menu - if they have dishes with truffles, give them a shot. It's an acquired taste but, once you like truffles, you'll love them. Another place we visited on our honeymoon.

Frontoni - A great tavola calda where you can get delicious pizza (really delicious) made your way "al modo mio", suppli', olive ascolane and other easy-to-eat favorites. We usually meet up my uncle here for the pizza. It's located in Trastevere at Viale Trastevere 52. Next door is a little gelato shop. From there, you can walk deeper into Trastevere.
