Well I have not checked this book out either, but I have heard about and seen his shows that have been on the Food Network. He seems to be very knowledgeable in the various cooking methods and traditions of the different regions of Italy from the past and the present. I plan to check this book out though, sometime soon. I think his show's are very informative on Italy's and the countries around the Medditerannian cusines.
Last year I ate at Babo,At that time it was marios new restaurant in manhattan. He also owns Po'It was a busy night and we sat upstairs (two level dining)it was a little cramped,But we had a 7 or 8course pasta menu with appropriate wines and I think it was something like $85:00 Per person,not bad for N.Y and at the newest hot spot. the portiones where small but perfect, beutiful hand made artision pastas.angalotti.gnocchi,parpadellas and the like.excellent bread and beutifal displays of antipasto.My only complaint was the service.A little presumpuouse(sp)I have not read Marios new book,but using Babo as a starting point I would imagine it is worth the bucks
