Fodor's Expert Review Osteria dell'Ingegno

This casual, trendy place—vibrant with colorful paintings by local artists—is a great spot to enjoy an ancient piazza while savoring a glass of wine or a gourmet meal. The simple but innovative menu includes dishes like Roman artichokes with baccalà, beef tagliata (sliced grilled steak) with a red-wine reduction, and a perfectly cooked duck breast with red fruit sauce. Outdoor tables (April–October) make you feel as if you're on an opera stage set, since your perch looks out over the Tempio d'Adriano (AD 145). If ever there was a place to linger outdoors over limoncello, this is it.
