Dinner at Liberty Tree Tavern. Crystal Palace is not what it used to be. The buffet really is not very good, and the character interaction is poor. It's very rushed.
The food at Liberty Tree Tavern is excellent. The meal is of course rushed (everything at WDW is), but nothing like at other places. The character interaction is better (during the most crowded time over Easter weekend in 2000, a couple characters dragged me out of my chair to dance). The food is served family style, and is your typical Thanksgiving type meal. It's great. LTT is also somewhat quieter than Crystal Palace.
