About 10 years ago an Italian friend took me to Livorno all the way from Florence just to have what she considered the best seafood in Tuscany. I liked it very much.  I don't know what the restaurant was called but I am going to be in the area in a couple months and would like to visit it again.  It had a proprietor that was very gregarious and visited the tables and made jokes with all the patrons (in Italian of course) which I could barely understand.  The portions were massive, and for dessert we had lemon sorbetto with some Limoncello to pour into it if we liked.  I am assuming it was a well known place since we drove there from Firenze.  If anyone knows of this place please let me know.  Thanks.
