As others have noted, this restaurant is a unique vegetarian choice in Taipei. The decor is striking, and it will confirm for you that you are about to pay a lot of money for food. Considering how cheap it is to eat in Taipei, it had better be uniquely tasty to justify high prices.
There are courses that can be paired up for you, and you can flip through the menus of these pre-set meals. You can also order a la carte. All the same, the food is expensive. Having been here a few times, I am never so impressed that I am dying to return. Instead, it's more of a celebratory venture to dine here. If I had to pay for my own food, I am very unlikely to come here.
The food is not all vegan, and in fact, most of the prix fixe menus are not… so, be aware. Chat with the staff, they will share what they know to guide you correctly. Nice dining experience, but not necessarily the most vegan happy eating. With so many green veggies in the eateries of Taipei, I am always disappointed here at the dearth of them - come on royalty, what did you eat?!
Cons: Price, Not all vegan
