A nice little find. Joyce Jiaozi restaurant is run by a very nice family from the very Northernmost Chinese province of Heilongjiang. Heilongjaing shares borders with Russia and Korea (they actually have some Korean-styled dishes on the menu).
The menu is extensive (perhaps 130 items) and is full of Northern Chinese specialties. They list 18 types of dumplings ("jiaozi") and a number of unusual items - including a full menu section dedicated to Chinese Shredded Pancake (a noodle-like shredded flatbread).
I had the Seaweed appetizer, Fried Pork Dumplings, Chive Pockets, and the Shredded Pancake with Lamb. Very nice.
The preparations are rustic and freshly hand-made. Best of all - you don't have to go to Richmond or Burnaby to get good regional Chinese! Joyce Jiaozi is located very close to Joyce Skytrain Station at Joyce and Crowley).
