We just loved BlueZoo when we ate there last November. The seafood was very fresh and top quality. The decor is stunning. My only complaint is we were there relatively late in the evening with one of the last seatings. The place was kinda dead. It's the kinda restaurant that benefits from a happenin crowd. But other than that, it was top notch!
Our other favorite restaurant is Citricos at Grand Floridian. They have a good mix of grilled meats and seafood. Great wine list, amazing service. Everything has a slight mediterrean twist. We've been dining high end at the world for the last 7 years. Of all the places at WDW, Criticos has been the most consistantly dazzling.
However neither are what I would call inexpensive.
If you're wanting seafood on a budget, I would recommend Narcoossee's at the Grand Flordian. They have a wonderful menu of fish and shell fish, good atmoshpere, and a wonderful view of the Magic Kingdom. Great place to watch Wishes or the Electrical Water Pageant. The prices are a bit less than Citricos and BlueZoo but the service is no less Disney.
On to Animal Kingdom Logde:
Boma and Jiko are both great. Boma is an all you can eat buffet and has a varried offering from night to night. The atmosphere is definatly more family oriented (ie lots of kids) than other places you've listed. The food is good and this format affords you the best chance to try several different African tastes. Since it is all you can eat, this is definatly the place for "healthy eaters". Jiko is a more formal sit down restaurant. The menu is good but a bit more eclectic that other resort restaurants at WDW. Both will be very crowded with hour plus waits so make sure you have an advanced reservation.
And finally Wilderness Lodge:
If you like the cuisine of the Pacific Northwest, Artist Point is for you. Trout, Salmon, and Buffalo are featured on their menu. The restaurant affords a good view of the pool and courtyard area at the wilderness lodge during the early evening. Go for anything stuffed with squash or pumpkin.
