My views are pretty much in line with others on this thread. We usually stay at Kidani when we are at WDW. Quite often, we go to Sanaa on our arrival day, especially when we are driving to WDW in the winter. It is very convenient for us, and the food is just right for that situation. I get the butter chicken which was already mentioned, and the lentil dal. My husband usually gets steak there, which he likes a lot. We get the bread service, which is excellent. It comes with about a dozen different sauces, ranging from very mild to two that are slightly spicy, but not too much so. It also comes with an assortment of round breads (semi-flat). If you do not want any spicy bread, the server will happily replace it in your order. If we are dining with more people, we will also get an assortment of small salads for the table (or 2 sets of small salads and 2 of the bread service, depending on the number of people).
Breakfast at Sanaa offers a great opportunity to see the animals just outside the windows. You order at a counter, and a server will bring the food to your table. It has a seat-yourself arrangement. We have been able to get a table at the window about 90% of the time, at breakfast. Your odds may vary, depending on when you are there and what time you have breakfast.
With regard to Jiko, just before the pandemic, we diid not really enjoy the meals we had there. So, we were a little slow to return after the pandemic. However, our last two meals at Jiko have been truly outstanding. As mentioned above, the atmosphere is more refined, though children seem to be welcome (and well-behaved, in our experience). We will be traveling with a 5-year-old on our next trip, so we probably will not go to Jiko. I believe I had filet mignon when I was there in January, with a very good soup as a starter. It seems a little weird to rave about the bread, but it is excellent. The service is very courteous. I don't think we managed to have dessert at either place.
Both Sanaa and Jiko are great restaurants. The service at Jiko is more elegant, but the prices are higher, too.
We generally work in a breakfast at Boma, and sometimes a dinner as well. We enjoy it a lot. Its atmosphere is a bit more hectic (reflecting a bustling marketplace), but the buffet offers the opportunity to select some tried-and-true choices and then to try a little that probably goes beyond your standard experiences. At breakfast, I have finally stopped selecting the oak-grilled tomatoes from the first station, because they tend not to go with the rest of my choices, even though they seem very attractive when I first see them (and they are good, actually).
