This dim sum restaurant has been around for a while now but I rarely come here with my family (... and will probably continue this way after my most recent experience). Century Palace is actually quite large with lots of seating so one positive aspect is that you will almost always be able to find a table here - no need to grab a number and wait (im)patiently in line as with all other Markham dim sum places. Decor is quite dated.
I came on the weekend. Dim sum here is served traditionally in carts so you have to wait for your favourite dim sum dishes to come around. Or maybe they will never come around - good luck! I found myself having to yell at the cart ladies to either tell them to stop (some will just rush right by you) or to ask them what they have. If you don't understand Chinese be warned that you will probably have a difficult time ordering the dim sum you want here. They do have a menu with rice/noodle options though.
Honestly the quality of the dim sum was not that great. Everything we ordered from the siu mai (pork dumplings) to the custard buns tasted mediocre.
If you decide to come here note that dim sum is cheaper before 11:30am so plan accordingly.
