This is Cha-An, one of my favorite Japanese tea houses in New York.
Simply delicious, fast and the service is amazing. They also serve lunch and dinner.
I tried many things on the menu and have never been disappointed.
If you like a tea you have tried, you can buy it individually.
My favorite is the Hibiscus Tea and the Genmai.
