Yeah, it's on the menu at Chez Hwang as "yang yum chicken".
I also know the korean bar on rené-lévesque corner mackay serves it. Really good also!
It's called "Yang Nyum chicken" on the menu. I tried it for the first time last week and it was really good. The chicken is crispy and the sauce it was in was sweet and spicy .
To my knowledge, they are the only korean restaurant serving this kind of korean fried chicken.
