If u want dim sum and don't want to have a long lineup, then Century Palace is the place u should go, cause it's big, so will make your wait time shorten. I suggest don't go if u want dim sum after 2pm, cause u may find not many dim sum available around that time. I found the taste of dim sum not always the same, sometimes taste good, sometimes not.....so u have to try your luck.
I like to go there because they have the sweet pancake that is not available in most of the dim sum restaurant, although not as good as the one my grandmom cooks, but better than none.
