This is one of those restaurants that have been around forever. In fact, my mom frequented it recently and told me that some of the old servers who used to provide her with BBQ when she was in her 20s are still working there! Pretty amazing, especially in Toronto where being "trendy" is everything.
There is a reason why Hong Fatt BBQ has been around almost forever. Their BBQ is excellent, possibly one of the best in Chinatown. Meats were suitably tender and the marinade for the Cha Siew (BBQ Pork?) is not overly sweet like some other places. Huge chicken wings - great for movie nights at home.
Would be improved if the interior was better kept. Hong Fatt is definitely a "hole in the wall". If you are turned off by dingy interiors, I would choose another place in Chinatown. If, however, you want to experience what Chinatown was like 30 years ago, this is probably the place to hang out along with KIm Moon bakery across the street.
