With extraordinary authenticity, this showplace in the Palace Hotel replicates the refined experience -- rarely found outside Japan -- of dining in a first-class Japanese restaurant. In Japan a kyo-ya is a nonspecialized restaurant that serves a wide range of food. Here, the range is spectacular, encompassing tempuras, one-pot dishes, deep-fried and grilled meats, and two dozen sushi selections. Kaiseki meals, eight-course seasonal dinners that change monthly, are also available, priced for an emperor. Sake lovers appreciate the dozen-plus labels, from the finest to the everyday.
