See.. you ask for opinions and you get three different ones..
I have been to Jiko's many times, I think it is noisey at best, darkened but noisey and when I went there last time, something was severely off. Not great service and the food came to the table staggered and one entree was lukewarm... I have not been back.
The last time I ate at AP, we had a good meal, service was good. I love the ambiance there and it is a bit more quiet than Jiko's. Although lately I have been reading reviews that are hit or miss..
Finally, my fave of the three you asked is Citrico's, which I reviewed recently.. The service was impeccable....food incredible, and one of the best dining experiences we had had on our whole trip, including pre WDW.. I will never stop recommending it as I have never not had a great meal there and I think when you are making dining reservations if you say that it will be two adults and you would prefer to sit by the windows.....they might try to accommodate.. I would seriously say that this is a special night for the two of you, it is, you are dining without the kids and want some adult time....and request a rather private window table for two.
