I have amassed some data from eleven XLB joints here: http://picasaweb.google.com/gustibus....
I can now pronounce (unequivocally) that my favorite Xiao Long Bao in the GVA is served at Lin Chinese Cuisine. The broth is thin and flavourful, the pork ball is light, and the skin is Din Tai Fung thin.
Close seconds are the XLB from Chen's (Richmond), Northern Delicacy (Richmond) and Wang's (Burnaby).
The trump card could still come from Shanghai River or Shanghai Wind where I have yet to sample this dish. I'll update as soon as I get a chance.
I know that management and kitchen at Shanghai Wonderful used to be the management and kitchen at Shanghai Wind. The owners could have very well taken their dumpling makers along with them when they sold to the Shanghai Wind's new owners.
Also I have tried the XLB from other places such as Long's Noodle House - but it has been a while. I am going by memory on some of these places. I didn't included them in this survey.
Good dumpling makers are traded and moved around like elite athletes so things could change at a moment's notice.
If anyone has any XLB recommendations, please post it here.
