I have been here a couple times now. Once, shortly after it had just opened for the day so just me in the store and another occasion after a movie had let out a bunch of people. Both times, I had great service.
Ambiance and decor is definitely attractive for a chinese bakery but most important is the quality. I find the Chinese breads to be one of the better ones I've tasted in town. The pineapple buns can be ordered with a whole piece of butter or half butter (perfect portion, I think!). The HK style milk tea was steaming hot and I really liked the brown sugar option because not many Asian places offer it.
I also tried their steamed rice - curry chicken - very good and filling! It doesn't look it but it was.
I am very glad to have this in downtown Markham. Though the parking can be a pain but I can't really fault the bakery for this.
