Once you have had good Peking Duck, it is hard to be satisfied with any other type or quality of duck. After my college days, I spent some time in DC where this high-end restaurant with an up and coming Chinese gourmet chef of acclaim in DC (I think her name was Jessie Yang) served the most amazing Peking Duck. Basically, when you bit into it, it would be crunchy but would melt away once it is in your mouth. It was also a burst of flavor. When I rave to people about it, they say that it sounds like confit, but I have had confit at Aujourd'hui and No.9 Park which does not compare to it. Alas, that store, Yanyu, closed down due to lack of business (really high prices).
Anyways, I mention this because after that store closed, I never thought I would have duck anywhere that would be nearly as good as that duck, but Chef Chang's world famous Peking Duck is famous for a reason. My dad, who is from Taiwan, and my fiancee's dad, who is from mainland China, both have heard of Chef Chang's duck and told me that it is actually a chain restaurant. So I had to try it to see. First time I went, I was tired so got takeout; the flavor was good, but the texture was not quite there. I wrote off the restaurant for a long time.
Recently though, I went back because my parents wanted to try this branch. Suprisingly, the duck was amazing. It was crispy and burst with flavor. I realized my taking it out had led to it losing that crispy quality. My fiancee and I went back several times after that always being sure to eat in the restaurant, and so far the duck has not disappointed.
We also tried some of the sizzling platters, the translucent fish, and veggie dishes. Overall, they were of good quality and good flavor, but nothing a gourmand would write home about. They were very much like dishes my mom used to cook. Definitely more authentic than any of the other Chinese restaurants in Brookline by far.
Pros: Best Peking Duck; Authentic Dishes
Cons: Don't take out the duck because it gets soggy
