I just went here for the first time today, and the food was absolutely wonderful, delicious, and complex! The restaurant, however, is not longer 100% vegan, but rather it is "organic." The owners, however, are completely aware of veganism, and so long as you mention that you are "vegan," they will give you only traditional vegan Japanese cuisine.
My vegan set menu for lunch (which ends at 2:30pm...not 3pm!) was absolutely delicious for 880 yen (a great price!~), and I will be going back tomorrow for more!~ :) They served traditional vegan Japanese okonomiyaki, which was phenomenal, and honestly impossible to find a vegan version of almost anywhere else. Lunch menu changes daily.
Despite the fact that it is no longer 100% vegan, the owners deserve credit for serving wonderful vegan and organic food in Osaka at great prices!! They even had vegan cheesecake for dessert.
