The main draw of this place is the cheap Dim Sum that gets even more discounted for seniors (10% if I remember correctly). And you can tell what the demographic is if you come on a weekday during the daytime. It's mostly all Chinese seniors. Not to be mean or anything, but I think they come because A) it's very cheap and B) maybe their taste buds have slightly declined over the years so they don't mind the sub-par dim sum. I know I sound like a snob, but I've eaten tons of Dim Sum around, including the Michelin-starred one in HK which is as cheap as some of the Dim Sum in Toronto.
When I came here we ordered tons of food. The best dim sum they have (not saying much) is their steamed baos (buns), where the buns are moist. For example, their Cha Siu Baos (BBQ pork buns) were the best things there. Their cheung fans (wrapped rice noodle rolls) were okay. The pastries (ie. BBQ pork pastries) are overly sweet. Siu Mai/Har Gow were not bad, but you have to get them fresh and eat them while they're hot otherwise they are rubbery.
If you're only considering value and not taste, this is the place to go, otherwise try the tons of other places in the area (ie. Casa Imperial, Dragon Dynasty, Crown Prince)
