My quick .02 on Kimonos:
1. It's good, and if I stayed at Swan again, I'd definitely go back - probably more than once during my stay. Again, It's good.
2. Some of the things on the menu seem nicely priced. Some of the things on the menu seem expensive. I would mostly order the things that seem nicely priced, because the quality is definitely there. IMO, those things were a pretty decent value.
3. For Disney World, I'd say it's a hidden gem. If you're struggling with finding a place to eat in the Epcot/DHS/Boardwalk area, and you like sushi, I'd say this place should be on your radar. It's not going to supplant your favorite 3 to 5 star sushi joint in your favorite big city, but for DW, it can be a surprisingly decent value.
