I have only ever had 1 good Italian meal in Disney World, and it was years ago at the 'non-Disney' operated Italian eatery in Epcot, Alfredo's Ristorante. I have since eaten a few times at Tutto Italia, Via Napoli, Mamma Melrose's, and Tony's. I finally stopped trying all together and don't get Italian on my Disney trips. I will fully admit my problem is I grew up in an Italian-American household in NY and that is what I am used to. I can enjoy Italian restaurants, even hole in the wall Italian pizza joints which are everywhere in NY and love it, but I just can't seem to find Italian I like anywhere else or at chains like Olive Garden or Carabbas. I recognize that I am difficult to please on this food front and the problem is mine. Luckily, when it comes to all other types of food, I am not like that and am not picky at all.
But anyway, I can't stand cheap jar tomato sauce or over-seasoned tomato sauce that places MAY make from scratch, supposedly, like Tony's claim, but thinks, when it comes to seasoning, to overdose the sauce. Less is more when it comes to things like oregano and basil. Cheap jarred sauces from like Francesco Rinaldi, Prego, and Ragu and others don't understand that. That being said, there are some more expensive premium jarred sauces like say, Victoria's which aren't bad at all - you get what you pay for.
Anyway, out of all the Italian I have had at Disney, Tony's was by far the absolute worst. They were worse than even Olive Garden. To me, even if they have been improved, they are probably now at best, at the level of say, Olive Garden, and I am pretty sure I still wouldn't like it.
