Having just gone in October, we didn't have a bad meal anywhere. It was our first time in Italy and the food was one of the main reasons to go back. We went from Tuscany down to the Amalphi Coast, up it, then back to just north of Bologna. Although the food is different in the various regions and some we liked better than others, my advice would be to take some steps inside different places and get a feel for yourself.
I am sorry for no names to suggest but really, I don't think you'll need any. The food there is simply in my opinion, the best of anywhere. General statement I do realize but I was smitten.
