The "three puppets," after which the trattoria is named, are the worn stone figures on a fragment of an ancient sarcophagus that embellishes a building on this byway near the Vatican. Little has changed here since the place was built in 1625, and the restaurant upholds a tradition of good food, courteous service, and reasonable prices. The menu offers classic Roman and Abruzzese trattoria fare, including fettuccine and abbacchio, plus pizzas at lunchtime, a rarity in Rome. The restaurant opens early, at noon for lunch and 7 for dinner.
