Gyoshintei was an exquisite experience. Located near the Rinno-ji temple, hidden amoung a confusing labyrinth of beautiful garden paths, the reataurant is a tranquil oasis in the sometimes crowded Nikko tourist scene. The setting alone is worth the experience: sliding screens, tatami floors, kimono costumed servers, Japanese customs and manners, and a wall of sliding glass doors opening on a serene garden. This is an experience to be slowly savored.
Both vegan set options provide an ample number of plates, all delightful. Take your time and enjoy the subtle variety of flavors. The presentation is itself a feast for the senses. The meals are not inexpensive, but if expense is an issue, it's well worth saving up for this treat. I don't think you will regret it.
By the way, ring the bell at the entrance for the hostess. You'll know you've found the right place when you see the entrance curtain with the three piece crown emblem. It would also help to get the tourist information people to trace out your route on one of their free maps. Don't hesitate to ask. Otherwise you might spend some time searching.
Cons: A little expensive, Somewhat hard to find
