Sorry for the late reply but I think that they only accept reservations via facebook from Japanese customers . I actually gave the contact of one of my friends in Japan instead of my own information. (+ I wrote to them in Japanese). They must've thought I was Japanese haha. Maybe next time you should try that instead.
Of course I know the restaurant.
It is one of the most symbolic Kappou restaurants in Kyoto (Kappou being a type of traditional Japanese cuisine).
The overall saltiness of their dishes is moderate and it is said that it tastes especially bland among Kyoto’s regional cuisine.
The dishes which are made by the owner are very tasty without relying on seasoning. I guess it would depend on people's preferences if they like it or not.
However, their lunch is great value for the price as you said and I think that it would be worth giving a try.
Starting with soup, there will be six creative dishes made using wagyu, followed by hand-rolled sushi, shabu-shabu, steak, rice（ramen）, and dessert.
All the portions are rather small, but there are quite a number of dishes.
