Although this might not be Martin or cousin Stephen Yan's (both stars of their own cooking shows "Yan Can Cook" and the Canadian version "Wok with Yan" respectively) quality of restaurant, it is fast food after all.
For under 6 bucks, it's a decent deal. The crispy chicken dish was on par with some of the better places I've been (see my pic). Had a decent serving of veg and the combo with the hot and sour soup. As long as you stay away from the battered deep fried meat with gloopy sauce (i.e. fake chinese food), I think you'll be okay. My buddies curried brisket was decent, and I've had the soup noodles with brisket which was right on par with any other congee type place.
Love being to get some decent Chrysanthemum tea that's not from a box or can, as you can't get it brewed everywhere (though admittedly it's probably instant).
It's one of the busier stalls at First Markham place food court, so get here before the noon rush.
