Good food near the hotel at "Antica Posta". I have not been for a couple of years now, but colleagues who have say it's still there.
Leave the hotel lobby, walk out to the main road - i.e. under a overpass, hang a right and walk along the road under another overpass, then up a small incline. After which you will cross a small bridge across a railway track. At the end of the bridge - there will be a small path in the bushes - walk down along the path and you will end up right at the side parking of the establishment.
Lots of crew have their meals there, QF,JAL,MH etc.
"Buon Appetito"
