Opened by the sons of celebrity restaurateur Sirio Maccioni (Le Cirque 2000), this less formal place celebrates the Tuscan cooking of their mother Egi. The contemporary menu offers a wide selection and includes some traditional Tuscan specialties, such as Egi's ricotta-and-spinach-filled ravioli, tossed in butter and sage and gratinéed with imported Parmesan. The pizza pazza (crazy pizza) has a delicate layer of mascarpone cheese and porcini mushroom sauce topped with thin slices of prosciutto di Parma. Don't miss the fanciful Circo desserts, especially the filled bomboloncini doughnuts. Reservations essential. Subway: F, N, R, Q, W to 57th St.
