We have only eaten at two...LTT and Crystal Palace...
I would probably rate Crystal Palace a little higher than LTT. It is a buffet vs. a family-style meal which means more options, especially for kids. The buffet itself is decent quality for the adults, plenty of meat, salad, veggie, desert options and a good area for the kids as well. And the character interaction is very good there although just the Pooh characters. At LTT the character interaction is a little better because you get the big hitters like Minnie, Mickey, Goofy...(If I remember correctly) all dressed in colonial America type outfits.
