Small and intimate, this quiet fish restaurant snuggled between Piazza Navona and the Pantheon is an outpost of high-quality seafood in the tradition of Anzio, the coastal town south of Rome the owner hails from. The menu has some sophisticated touches, such as oysters tartare, snapper with foie gras, and pasta dishes made with toothsome Gragnano pasta. There are precious few tables in the tiny dining room, so make sure to book ahead. Reservations essential. Jacket and tie.
