This is the only Chinese restaurant I would recommend to other Chinese people.
In other words - its authenticity is undoubtable. We invited our friends on multiple occasions, to great effect. Just recently they renovated their upholstery to soft black booths which increases the sense of privacy. This is definitely one of the more quiet Chinese places. We come whenever we want to excite our tastebuds. Our favourites are the sweet pineapple sticky rice with honey and coconut milk, as well as their mushroom and other spicy meat dishes (such as the house special grilled fish). There are a lot of Chinese dishes you will not find anywhere in Calgary, moreover this side of Canada.
I won't say that everything on the menu is equally delectable, but the waitresses know the menu front to back and they will be able to identify their best dishes (their recommendations are never off the mark). Yunnan has some of the spiciest food, so maybe be careful and trust those red pepper signs. This is always a baby/kid friendly place and it's usually not hard to get a spot for lunch, maybe harder for dinner. Can be more expensive than a HK cafe because they use some rare ingredients and have dishes that have to be pre-ordered as they are prepared from scratch by order.
The place is owned by an old couple that just really loves to cook, so it's just really cute and I would love to try more things on their huge menu.
