Apprivoiser

I wanted to have breakfast there but I was a little late and ordered a vegetarian lunch instead. All tasted very good and the service was nice too. (English menu and English speaking staff.)

A great find for vegans, or omnivores who like healthy eating.
Location: across from Sunroute Hotel on Kawaramachi-​dori btw Matsubara-​dori & Takatsuji-​dori, this is easy walking distance from the river and Gion or Gojo metro station. There’s an awning, sign & menu chalkboard outside with the name in English. The place is easy to find, unlike many in Kyoto!
Ambiance & menu: the ground floor café is open for breakfast, lunch and desserts (8AM-​7PM) and has organic coffee, tea, smoothies, muffins, scones, biscotti, sandwiches & free wifi. We had the vegetarian lunch special (1000 yen) a generous and tasty serving of miso soup, green salad and soy nuggets, brown rice, carrot-​walnut salad, kinpira, and pickled veggies. The atmosphere was welcoming, the service quick and the hosts and menu are bilingual. This has become my go –to place in downtown Kyoto.

It is very tough to find a restaurant in Japan if you are vegetarian.
I can suggest a solution for you, Apprivoiser.
Apprivoiser is the restaurant serving special Japanese style Set menu, drinks and smoothies. They use only organic vegetables and they also have some non-​vegetarian menu.
I knew this restaurant for a while because I’ve always been passing in front of the place. I wondered whether this is a good place or just an ordinary café. Today, I missed lunch and it was already after 2:30 pm. I was not sure they still serve food but I asked «They are any chances to have food at here. They said «Yes, we still do» so I just jumped into the restaurant.
There was a patron at there when I visited. It is not a busy restaurant. Anyway, I choose today’s set menu, the main dish is Deep fried soy meat with Ponzu sauce. It sounds not tasty but I would like to try. It was much, much better than I thought.
A chef, Ai said they have many foreign vegetarian guests who have difficulty finding proper vegetarian restaurant in Japan. They cook food for each guest carefully so you can feel safe even you have some limitation to have meals.
This place is an oasis for vegetarian who bored to have Udon or Salad in Japan.
