Since you are paying OOP, generally avoid any restaurant that takes
DDP -- that includes the Disney Signature Restaurants. They have all declined in quality as a result of DDP, and the desserts at all of them are disappointing or worse.
So, among the really nice restaurants,that leaves basically:
V&A
Shula's
Kimono's
Blue Zoo
unless you go off property, which is rather inconvenient.
If I wanted a knock-out dinner, I would go to V&A. The food is amazing. It is out of this world with wine pairings. But, even without, it is by far the best meal you will find anywhere in Central Florida.
If you really like steak, then go to Shula's. Dh and I dined there a couple of months ago, and I had what I can only term the best steak of my life (other than the Japanese wagyu beef at V&A, which is in a class by itself). The other items are delicious and first rate, too. We love the barbecued shrimp, the creamed spinach, the salads, the soups, the chocolate souffle. It's all great. The only issue there is that it can be noisy and not very romantic -- especially if one or more convention groups are dining. Still, the steak makes up for a lot of other issues.
We recently dined at Blue Zoo. While it was good, we would pick one of the other two. We felt the wine list was lacking, but that would not matter to you.
We like sushi but avoid Kimono's because we hate karaoke.
We used to love CA Grill, Narcoosee's, Jiko and Artist Point. We don't bother with any of them anymore. We also have given up on Bistro de Paris.
We like Citrico's but have found it wildly noisy. And, the best food and ambience we have had there is when we got together with friends and reserved the Chef's Domain. That takes 4-6 people, however, for it to make economic sense.
We recently did the wine dinner at the bar at Flying Fish. That was fun, and the food was very tasty. We would do that again. But, it might not be as fun without the wine pairings. Still, I would consider it, though you sit at the bar with others, so not very romantic.
We have had very tasty meals at Fulton's, but it is now on DDP, unfortunately, so it is off our list or soon will be.
We have to face it. Except for a few notable exceptions, truly fine dining is a thing of the past at Disneyworld.
