I was there for dinner on September 16, 2017 and I am reviewing for both the Peking duck and the customer service.
The peking duck deserves a 4/5 or even higher. You do get what you pay for. The roasted duck had a nice amount of fat and the meat was tender and moist. The skin was exceptional, nicely crisp and not burnt. We had the flat pancake which was also very moist and soft. They gave us spring onions and hoisin sauce which complement the dish well. The meat portion, they made a savoury pastry consisting of the duck meat and diced carrots and celery. Overall rather good.
In terms of the customer service portion, I have to give it a 2/5. Granted we were sitting on the second floor. We had to wait about five minutes to even order food, even though we flagged the staff several times. Did they forget about us? Not sure. Then, as we wanted to order bowls of rice, it came about 10 minutes later but that's because we once again had to flag them down asking for the rice. The dishes were all cold because the rice never came. We were not impressed with the service as we seemed to be ignored.
Overall, the food is great. We had other dishes as well such as a tofu casserole dish and sweet and sour pork. But the customer service really through the ratings way down. Get your A-game on and improve the service please.
