I went here last night for the first time, and for 2,000 yen, had an absolutely delicious dinner, which consisted of a vegan quiche with Japanese pickles, a savory quinoa/pumpkin/potato pastry, a delicious plate of edamame/soy bean curry, and organic coffee/tea at the end of the meal.
Totally satisfying, and I would go back anytime for dinner. Menu changes daily (there were multiple options to choose from, for both the appetizer and the main dish).
Furthermore, the restaurant is no longer "vegetarian," but is now 100% vegan, which is great! The couple that runs the place are absolutely cool and friendly, and the decor and ambiance of the all-wood traditional rustic Japanese style made the restaurant a pleasure to dine in. I would go back anytime! :)
