This place was formerly known as "Mong Kok Chinese Restaurant" and it was a full push-cart dim sum place (all dim sum pushed on carts). It was relatively decent and good service.
Now they use a paper-form ordering system, along with some carts that mostly carry deserts or high-profit margin items they want to peddle you with. Unfortunately, with the new system they are quite buggy, slow and sometimes forgetting items.
There's a few paper-form ordering dim sum places in the GTA that does better in terms of speed, quality and price. I was only willing to pay a premium before, because of the full push-cart system, so I will not be returning anymore.
