This food stall inside First Markham Place probably has one of the best BBQ food in the GTA. The only ones I can think of that can compare to that are King's Noodle in Chinatown (and even that the quality has gone down) and a BBQ food stall in Alton Towers Circle in which I forgot the name.
Their BBQ pork and soy chicken are the two musts for this place. Whether you want rice to add to that is up to your discretion, although I'm not much of a rice person so I usually just have it stock take-out.
Service is, well, typical Chinese quality. Again, it's just a food stall, don't expect valet treatment...or any treatment for that matter.
