The restaurant in Japan in Epcot. I forgot the name of the restaurant. Sorry!
But, you take these stairs up to the second level and there are 2 restaurants in there. One for hibachi and the other for sushi. They're great and fresh!
Living here, and having eaten sushi in all of the above restaurants, the true answer is this...Kimonos in the Swan hotel is not only the best sushi on Disney property, it is the best sushi I've ever had. California Grill is Great, Wolfgangs is very good as is Toykyo Dining. None of them compare to Kimonos.
