The real reason to go is for dumplings. You can actually see them making the dumplings for you. The dumplings are generally above average and the only reason I don't give a five star is because the owners are a little stingy on the filling. We have tried several varieties and have never been disappointed.
As for the entrees, we have not liked most of the ones we tried. They are below the quality we can get elsewhere. We did like the fried Shanghai new year's cake.
The description in the other review of the service being cold but efficient is accurate. The place is very clean.
We have returned many times and will continue to do so.
