Without question the best Italian restaurant in the world is in Catania. I assume it's still there, I haven't been there in 5 years. It was called the Trattoria Rinaldo. If you're at the hotel that I think was called "The Palace", (you'll know it because it's the nicest hotel downtown) go out the front, turn right, go 2 or 3 blocks then it's right another 1 or 2 blocks. Look for the red hanging sign.
