I don’t know what Hakkasan is supposed to be. A lot of the dimsums and the ingredients used are not Cantonese standards. A mish mesh of influence from all provinces and fusion.
The service didn’t carry over though. You can get your nails done in China but here you just eat.
BTW, I guess you don’t count local chains. Otherwise the list would be much longer with for example our own homegrown dumpling chain- kingdom/ empire/ depot, etc. etc.
