Go to Celebration, Florida
If you want to eat outside of the Disney parks I recommend driving to Cafe D'Antonio in Celebration. This charming town is a planned Disney community and a short drive from any of the Disney parks. We love Itallian food and think that Cafe D'Antonio is wonderful. There are several other restaurants in this town and just driving your parents around this community should be a treat. We also like the restaurants on International Drive such as Oceanaire Seafood or the Capital Grille (both are a little pricey) and Maggiano's is a fun place for family style service.
