As with other reviewers, it should be noted when you go to a Chinese establishment that you should not expect exceptional service. With that said, the staff definitely felt more disconnected than your average joe Chinese restaurant to a point that their job could very well be replaced by an iPad and conveyor belt.
The food itself is quite standard and has huge proportions for the price. If you are looking to feed a large group on a budget without cooking at home, Congee Queen is definitely a viable option if you are in the Richmond Hill area.
