If you have been there a few times, you may have already hit most of these. If they like a special type of food, that could help narrow it down, especially if you like something in one of the countries at Epcot. I know we went to Boma last time and 2 of us loved it, two, not so much. But so happy we saw AK Lodge, its so beautiful. Its hard to please everyone. Pizza, steak, and buffets work best for us.
Everyone has their favorites, and its hard to eliminate those, but we are trying 3 new ones this time, and taking off a few that we always go to.
