I think the dim sum here is pretty good. This place tries to insert itself into the higher end of dim sum. The decor is all grande and Victorian (I think). The space is huge, which makes sense why they close off a big portion of it for the dim sum hours since they can't possibly fit it all.
The dim sum though I think is better than average. They also have a few items that are special. I like the fried chicken knuckles.
I've come here quite a few times and find getting a seat rather difficult. I've also found that their parking arrangement to be lacking for the amount of people inside. Though now I think there must be less people going because I guess there appears to be enough.
As a convention centre for wedding banquets, I've had some good wedding banquets here. I was quite impressed with the flavor, quantities and quality of the food. Though it's hard to compare because it's all a matter of how much the groom/bride paid.
I'd come here again, in fact I have! It's not cheap for dim sum ($60 for 3 people) so it is on a higher end spectrum.
