Peking Duck should be your number one reason to patronize Chung King.
I have been to Chung King many times. Every time we ordered the Peking Duck. I don't even bother to review the other dishes, cause the quality of everything that is not Peking Duck fluctuates from authentic Chinese food level to Americanized Chinese food level, from time to time. Sometimes there is a reasonable amount of MSG, sometimes there is a lot. The Peking Duck, though, is consistent. It is also authentic. Is it the best in Toronto? Not in my personal opinion. Yet the overall pricing, free garnishments, combo, etc., offers a good valued, authentic Peking Duck meal.
Cash only. Reservation recommended for weekends.
