I found Chinese cafe "Anding" at the Kami-tori. This cafe is small and it is difficult to find because of 4th. floor in the building.
I went to have a lunch there and ate porridge. There were several kinds of lunch sets and all lunch sets were put with Chinese tea. Porridge was with some vegetables and plain taste. Chinese tea was really good fragrance. Even though the cafe was in the 4th. building, there were many customers and I was surprised it. Also,they sell Chinese sweets. I will try next time!
