Mò Mò Republic is both a restaurant and cultural center located in a renovated historic villa in Monteverde Nuove. The restaurant is known for its simple, high-quality Italian cuisine (you MUST try the fettuccine with mushrooms and truffles), good prices, and modern but casual atmosphere (in other words, no fancy dress required). If you're going to staying in Rome for a while, check out their website from upcoming events like movie nights, book signings, etc. You also have the option to become a "citizen" of the republic and enjoy membership discounts. The only drawback is the location. It's located a good ways outside of the city center but there is a good mix of transportation options so it’s still fairly easy to reach.
