A friend of mine researched and found this place in Ikebukuro after seeing some Food Network Tv show where the host was eating a bizarre ice cream flavor here in Japan. Ice Cream City in Sunshine City is said place.
I do not like ice cream, but when I saw flavors such as Potato and Butter, Miso, I had to give in. I did not try the Ox Tongue in the picture above.

Bring a camera! Just outside the Cup Ice Museum are several additional places to purchase ice cream treats. Those places have more traditional flavors, but they have unique presentations.
