There are too many great sushi restaurants in SoCal that cost a lot less.Granted,it would be a nice place for someone from out of town to eat at.But I know of a LOT of great places that cost a lot less for great sushi...
I agree with what pretty much everyone else has said about the restaurant, except the prices. If you go in there expecting to pay that amount, then it really isn't that bad. Having eaten at Katsuya at the Americana I can say that expensive Japanese dining isn't exactly limited to Disney restaurants. Quality-wise, though, Katsuya and Yamabuki are very similar, though I think Yamabuki wins because its service is simply bar-none compared to many other restaurants (Disney and non-Disney alike).
Another thing that puts it ahead of other places is the Tetani (?) room. There aren't very many Disney restaurants that offer that kind of experience, and it's a shame that that's going to be lost.
The prices seem on par with more 'upscale' sushi place. Yamashiro and Matsuhisa come to mind, definitely not overpriced in terms of fine dining.
Probably not when you talk about "fine dining", but I don't think anyone connects those dots when it comes to the Paradise Pier Hotel. And when you're on vacation, that really is a lot to be spending on food, especially in our current economic climate.
But even at the fine dining prices, I think it would have done better in say disneyland hotel or downtown disney.
It's been a few years since I've eaten there, but I really enjoyed PCH Grill. I once had this duck and goat cheese quesadilla with BBQ sauce that I loved there.
There will probably be some mixed oppinions about this, but for sushi I really enjoy Kabuki. They seem to have restaurants all over southern California and they're reasonably priced. Maybe they could put one in DTD sometime?
