"Following careers in fine dining in Italy and abroad, Leonardo Vignoli and Maria Pia Cicconi went back to basics with Cesare al Casaletto, a straightforward trattoria the husband-and-wife duo took over in 2009. The menu features Roman classics with a few restrained twists, like fried gnocchi served on a pool of cacio e pepe sauce. The pasta alla gricia has achieved cult status, the suckling lamb mains are exceptional, and the beverage list spotlights stunningly affordable natural wines from Italy, France, and Slovenia. If you take public transit: Take tram 8 for easy access, and stroll back to the center through Villa Pamphili park after lunch." - Katie Parla
