I've visited this restaurant on my last two visits to Osaka. I found the food delicious, and the owner friendly and very passionate about his cause (educating homeless children in India) so I was happy to eat there and support it. So I'm reluctant to write a somewhat negative review, but feel the need to warn vegans to watch what they eat there.
On my last visit, nearly two months ago, I was assured that their vege meat was vegan, and as such I ordered a set meal with it. Always mistrustful of fake meat (which usually contains milk, often egg and sometimes worse) I left the slither of fake meat on my plate. Otherwise the meal was delicious.
After my meal I explained to the owner that I have a vegan blog (true) and wanted to promote his restaurant on it, but first I needed to be absolutely sure that it was vegan, and that fake meat often isn't, so I asked if I could see the packet it came from. He quickly got it out of the fridge, and when I checked the ingredients it contained milk protein. The owner seemed genuinely surprised and apologetic, and explained that he had been assured by the supplier it was suitable for vegans (and he said he couldn't read the ingredients himself).
He asked for my email address, and said he would check with the supplier and let me know. It seemed a bit strange since the ingredients clearly stated it contained milk, but he seemed genuinely concerned so I gave it to him.
It's now been over a month, and I haven't heard from him. I also see soy ham still listed on their vegan menu, and another reviewer here saying he was served non-vegan food after ordering vegan within the last year. So I guess it's possible he's replaced it with another vegan soy meat (though I don't know of one in Japan), or there's some other explanation, but for now I just want to warn vegans to stay away from the fake meat (whatever you're told), and to be careful to ensure that your meal is vegan.Pros: delicious Indian food, fairly priced and supports a good cause, convenient location
Cons: dubious vegan food, small, underground location
