Im a big fan of pasta...but nothing really fancy. Unfotuantely I have found its difficult to find a good plain pasta(ie not mixed with any kind of fish) in WDW.
The one I really enjoy is the Penne alla Vodka at Mama Melrose. Its delicious! In fact, Im making a special trip to MGM at dinner time on our 1 park day during our next trip just to get that meal.
