Felice a Testaccio is a restaurant in Testaccio, Rome, serving traditional Roman pasta such as cacio e pepe and carbonara. It also offers amatriciana, Roman-style artichokes, and lamb dishes. Staff mix the cacio e pepe at the table, and the wine list is separate and varied. Without a reservation, a long line forms, and one case involved a wait of 2 hours 30 minutes.
