When I arrived Arashiyama, the first thing I did is to find the Arashiyama Yoshimura and reserve a seat. Even I make the reservation at 11:30, I still need to wait 3 hours to come back. It's not that easy to find it. It located in a yard. When you see the sign in the first photo. Just get in, and you'll see the door of Arashiyama Yoshimura as above. Find the waitress to book a seat.
It has the Mandarin version of the menu which is helpful for me to decide which I want to eat. Just order the most popular, Togetsu-Zen.
The Sansai Soba. The vegetables are cooked really simple, try to keep their original taste. The soba is not a strong taste food, either. Slow down and eat with your heart, enjoy the natural flavor of the foods.
