Here's a little background before I begin - my dad's family was from Beijing and I lived in Beijing for a while. Having been spoiled by my grandma'a delicious home made dumplings, I can be pretty harsh in my criticisms.
I only tried their dumplings (all of the flavours) and some of their cold dishes. I really like the pork belly with vinegar and soy sauce dish. It reminded me of food I had in childhood. A little bit too salty though.
As for the dumplings, I can only say it's standard. The flavours are nothing impressive, and can be a little bland at times (especially after a very salty appetizer). In Toronto standards, it's probably 4/5 or even better. It's just not that plump. Juice wasn't that abundant. And the dumpling sizes varied a bit in each tray. I guess that's what you get from hand made.
Anyways let's not be harsh with them. This is so far my fave dumpling place in Markham. Food is cheap and very filling.
Some young girls working there got bad attitudes. But that's usually the case at cheap eats.
