We had lunch at Tonys this past October and enjoyed it very much. We are Italian and I cook Italian (learned from my off the boat Nana)... and I thought the food was very good (not the best). One problem was there was too much dressing on the kid's salad. Besides that, we were pleasantly surpirsed. Very traditional foods. Nothing fancy. And we don't like fancy.... The menu at Epcot is very different. They have a different take on Italian food. Very fancy. Very expensive. Wonderful atmosphere. You are paying top $ for top foods. And many have not been happy with the food there either.
I really don't think you can compare the two. But if you are looking for some pasta go to Tonys. If you are, looking for an experience go to Epcot.
