If you like beverages made of green tea, japanese sweets or japanese snacks, you have to go to Koots! Since Koots is a chain with a growing numbers of stores in Tokyo area and has a green logo, you might say that Koots may become for green tea what "Starbucks" already means in the world of coffee.
I visited Koots in Roppongi twice in the mornings, and it was really quiet. I really was able to relax and enjoy the green tea.
Favorite Dish: I tried "matcha latte" with "dorayaki" as well as "onigiri" and a cup of regular green tea. Everything was fine, and the price is reasonable and comparable to those of the big coffee-to-go-chains.
