We have found the food to be really good at Tusker House, Flame Tree BBQ, and Pizzafari (pizzas only). However, if you're looking for "fun," I'd vote for eating outside at TH. Every time we've visited, there have been perfermors (musicians, dancers, etc.) in front of TH. During a Christmas visit, I ate my breakfast while watching some singers/dancers. Near the end of their performance, they involved a bunch of kids from the audience. If you grab a seat a little before the parade, you can watch the parade from underneat the covered seating area.
If you want something a little more quiet, the outside dining areas behind FT are beautiful! We love watching the large birds (herons and such) wander around the large, ornamental ponds.
