Try their shaobing with tofu skin and basil. Their almondtea is also pretty divine. Not so busy in the mornings, afternoon and dinner time I recommend booking in advance.
Try: noodles, misobean curd. It's not the traditional type of Chinese vegetarian food (ie the boring type with many food additives trying to make bean curd rolls to look like ham).
Decent choice for a vegetarian/vegan meal in 東區. Flavors can be a bit bland. Soymilk is nice and creamy. Potstickers are decent. Accepts credit card. 10% off on Mondays for meatless Mondays.
