I had been eating at their restaurant in Seattle for years, always bringing many friends with me for dim sum and the owner is consistently rude and impolite. They are no longer in Seattle and haven't been for years so make note of that.
Who wants to be treated badly when all you want is to enjoy your meal and have a good time with friends. I finally swore never to return but why would you have to since Jade Garden is the best in town. The ingredients are much better and after eating you feel good all day.
I agree with the folks who also got the rude treatment that posted that here. Go elsewhere and maybe they'll get the hint one day.
