They were very generous with the free tasting. I usually am not a fan of sake, but this I really enjoyed. It may have been just from the fact that we were in a place which seemed to border on magical and we had just walked 2 or 3 miles from the monkey park, but this sake tasted quite good to me. They were also extremely helpful and informative in explaining the different styles and how they differed in their manufacture. The same company also owns Shiga Kogen beer brewery, located just a couple of blocks on down (thankfully on the way toward Shimaya). Their beers are quite nice, also.
