Hereīs another recommendation:
Anni Cinquanta
Via Flavia (just off Via 20 Settembre)
Tel.: +39/06/42010460
As the name suggests, this Pizzeria is designed in a 50s style, but thatīs about all there is to the name... It is bright, pretty new and very clean.
However, this Pizzeria is frequented mostly by younger Romans (never spotted tourists there) and they serve a delicious range of Pizze for a very reasonable price. You can also get great (!) Panzerotti there - these are deep fried Pizze made of a special dough. They are not to be missed on a trip to Italy, but not typical for Rome, so a little hard to find...
