I wrote unique restaurants in Tokyo in 2004. After a long interval, I will update today.
Absolut Icebar Tokyo
It is the first permanent icebar in Japan. The bar is kept at minus 5degree with crystal clear ice transported from Torne River in Sweden. The bas is operated in 45 minutes time slots and you can use warm jackets and glove by 3500yen. I readd it is very hard to make reservation there. It's very nice place for humid summer in Japan.
I wrote about this place before. This bar is produced by a famous Toy collecter Teruhisa Kitahara. And you can see great figuar created by Shinichi Yamashita and waitress serve costume inspried by Yamashita's figures. I went to there to write an article for Japanzine before. I can't say it's reasonable and smaller than I supposed. But it's nice for topic.
Taketori Hyaku Monogatari
Taketori Monogatari is 8-9th century Japanese folk tale about a mysterious girl, Princess Kaguya. It is also known as The Tale of Princess Kaguya. Shortly story is... A small beautiful baby girl was found by a bamboo cutter when he cut a shining bamboo. He brought up her as his daughter under the name Kaguyahime, "The Shining Princess." He becomes rich and urges her to marry one of five noble guys, to each of whom she sets a fantastic quest: all either refuses the suit of the emperor. Eventually she explains that she is from the Palace of the Moon, whose messengers are coming to that her back....The restaurant has misterious mood with bamboo. You can enjoy Tofu dish and Charcoal Grilled foods. Hmm this the Moon room is interesting.
This restaurant based on the Japanese folk "Urashima Taro". The story is here. Actuallly I have not gotten the precept of this story still now :-) Wiki said there are some similar folks in the world. By the way Ryugu is the beautiful palace under the sea where Taro went with the turtle. The restaurant made such mood in their floor.
