That depends on what you consider "good Italian food". If you like Southern Italian cusine, come from an Italian family, and don't usually find what you consider good Italian food when you go out to dinner, then you will not find it in WDW. If you consider Olive Garden or similar restaurants to be your ideal, then you may find what you're looking for in EPCOT, Tony's in MK, or Mama Melroses in the Studios. Your best shot will be in the Italy pavillion of EPCOT.
