Located next to the Atago Torii (a large Shintō shrine gate), this thatched-roof restaurant is about as atmospheric as they get. It serves a simple cup of matcha for a relatively modest ¥840 (it comes with a traditional sweet). It's the perfect way to cool off after a long slog around the temples of Arashiyama and Sagano.
You can also sample full-course kaiseki meals here from ¥11,000 (by telephone reservation in Japanese only). Its speciality is ayu (sweetfish caught during cormorant fishing).
