I've just found a secret spot in Kyoto.

I went there without knowing, just because the food looked good and cheap in the resume on Google map and I want to visit a temple in the neighbourhood later. I got a bit surprised when I entered the building for how luxury it looked, and even more when I realised the price of the cup of coffee at the counter. Imagine a cup of Geisha the price of a Kopi Luwak. They don't tell it right away (trap) but there are soft drinks, at reasonable price. So, if you don't get caught in buying a coffee you end up with a reasonable price and yet tasty drink and sandwich in a wonderful traditional Japanese style building. Also there was nobody at all, a full 8 seats room for me alone ! Everybody probably get scared by the luxury look and coffee price. Given it's located in the busiest tourist district of Kyoto, it was really a surprising experience to spend a quite moment in such a luxurious place for the same amount of money I would have spent in another standard coffee of the area. And if you can afford it, they also seem to have great coffee, but I read they serve it in paper cup which is quite a shame and makes me less guilty to have not fallen in their trap.
Bonus point, for ten minutes a beautiful butterfly was flying in the garden right in front of me.
If you can I recommend you come here, but do it quickly, being empty a Saturday afternoon in such a place surely mean they won't last long...
