My family's favourite and go to place for dim sum and big family dinners. For dim sum, their rice noodles are very smooth and perfectly steamed so that they aren't soggy but soft in the same time. Another favourite dish of mine is their BBQ-pork Mellon buns. This isn't on their menu so you'll have to either ask the waiters or wait until they bring some around asking if you want any.
Their dinner menu has a vast range of options. Most of the dishes are not cheap but comes in very large portions. I highly recommend coming as a group of 4+ for dinner and ordering "fish tail" (sorry, don't know what's it's called in English)
