Of the three, our fav is Hooke's Point, however seeing the other restaurants you have already booked, I would go with Yamabuki. HP is mostly seafood, but that is part of why we love it so much
. Anyway, the sushi at Yamabuki is very good, and fairly overpriced but all the restaurants at Disney are. I wouldn't eat there if not having sushi - last time we were there one member of our party ordered the steak. He got about 5 ounces of sliced steak with mushrooms, one scoop of white rice and a broccoli garnish (which he didn't eat) and was still hungry. And it cost about $25. But the restaurant itself is quite lovely, quiet and peaceful. We have enjoyed all four times we have dined there. Good luck deciding and have a wonderful trip.
