Just a few thoughts.
Jiko is my favorite restaurant at WDW. Beautiful restaurant, excellent food, great wine list, warm attentive service. It is one of the quieter WDW restaurants. In October I didn;t see any children the night we were there. It was very romantic and we enjoyed a bottle of wine recommended by our server from their wonderful wine list.
I would choose Narcoossee over Citrico, but I agree that Citrico is probably quieter and more romantic. The food at Narcoosee appeals to me more. You can see Wishes from Narcoosee, but it can be noisy.
I thought Flying Fish was excellent. I haven't been recently, but I definitely will return there.
After a couple of tries we will not return to the Yachtsman Steakhouse. Our meals were just not good. We were 3 adults, we ordered 3 different entrees and we all were disappointed.
We love the food at Teppan Edo in Japan. But you sit at tables for 8 and are entertained by the chef as he grills your dinner right at your table. You will be seated with strangers if that is an issue for you.
We found the food at Marrakesh (sp?) to be very good, but we do not know "authentic" Morrocco food. It is a beautiful restaurant, with good food and warm attentive servers. The belly dancer and band are fun too.
DH does not like French food so we have not eaten in either of these restaurants.
Congratulations on your upcoming wedding and have fun planning!
