Crystal Palace is a buffet, Liberty Tree is "family style all you can eat". The menu at Liberty Tree is salad with strawberry vinaigrette, mashed potatoes, mac'n'cheese, green beans, turkey, ham and flank steak. Dessert is apple cobbler. We ate there 3 times this past year and that was always the menu.
We had dinner at Crystal Palace on Christmas Eve and the food was good, a lot more variety than at LTT. Many types of salads, meats, veggies, great dessert bar too.
However, the characters are better at LTT in my opinion.
