We love Kouzzina, but it is closing on September 30th. If your trip is before then, that would be my suggestion. We went there for our first dinner last time. We always stay at BWV, as it is our DVC home resort. We also love Yachtsman Steakhouse at the Yacht Club if you're looking for a signature, highly recommended! Excellent steaks and great service. We haven't yet been to Flying Fish, but I keep reading outstanding reviews on it. We're going there on our upcoming trip in July. I heard they make a great steak, in case you're not into fish, and they also have a pork dish on their menu as well as a vegetarian option. So plenty of choices even for someone who doesn't feel like eating fish. Some people say they have the best steak on property! If you're looking for CS that night, Picabu at the Dolphin has good food. It's not on the dining plan though. But if you're a DVC member, just show them your DVC member card and you get 20% off. I also sometimes stop by there to grab a quick lunch to bring back to the BWV pool area, on days we're just relaxing by the pool and not going to a park. It's a very short walk to get there!
