Another vote for Coral Reef. We've had dinner there several times and have never been disappointed. Yes, it can be a little loud due to the acoustics of the place but hey, its WDW...there are children and there is noise. The food and service have always been great. There are several threads started every year by people claiming that they've heard or read horrible reviews and I wonder where and why are they hearing this.
We love having the wonton soup with delicious crispy noodles on the side at Yak & Yeti- then we either split the beef stir fry dish (not sure what it's called, but very big portion) or we order our individual fave dishes.
Kona Cafe (tonga toast), Kouzzina (breakfast and also the seafood stew at dinner is wonderful)..and here's one for ya: the Cabana bar which is poolside at the Dolphin - they actually serve a wonderful lunch and they have an awesome beer/drink menu. Really has a Miami feel to it.
