Is this the one within the mall, on the 2nd level? OH, wait, I think I know what you're talking about... this is the one that was converted into a dim sum place from the buffet!!! 'Coz it used to be called Rex buffet as well...
I would say the dim sum is about par with Perfect on the next block and the prices are about the same. They also give you a frequent card with one check for every $10 spent.
This location has seen many iterations. Let's hope this venture is successful.
