I use several Italian Guide Books to prepare for my
trips to Italy and found these to be quite reliable.
They are in Italian but armed with my Ital-Amer
Dictionary I stuggle through the write-ups. In Catania:
Antica Marina; Cantine del Cugno Mezzano; La
Siciliana; and Pagano. South of Catania in Augusta I
would try Donna Ina. In Siracusa Arlecchino looks like
a good bet and La Frateria is the best pizzeria in the
city. Many years ago I ate at Darsena da Januzzo which
is located on the port. No doubt you will be driving
down to Noto. There I would go to Trattoria del
Carmine. I have never had anything but terrific food
in Sicily. Most restaurants are small and not at all
expensive. Get ready to eat great fish along with
excellent fruits and vegetables.
