Coffee Sakan Syu is a coffee shop chain so you can find this place all over Tokyo. The one I tend to visit the most is located in Shibuya but I also like the one in Yurakucho too. The premium blend coffee I order is a heavily, tasty coffee that you will be addicted to.
They have a menu in English if you are not able to read Japanese.
If you order a cake you can have your coffee with a 200 yen discount. For example, the cake is 600 yen and the coffee is 750 yen but if you order them both together it will be 1150 yen in total.
It is located on the second floor of the building in front of the OIOI building adjacent from the JR Yurakucho station.
After walking around and finished with shopping, having the premium taste coffee is so nice.
