Tastes kind of processed. I don't think they hand form the patties from ground beef. They probably come from a factory.
On the plus side, lots of interesting toppings to choose from. For a fast food burger joint they're not bad, but I wouldn't say they're good either. Toronto is a burger city and there are a number of better burger spots to choose from like Craft Burger, Burger Shoppe and W Burger Bar. This place is cheaper than those places though.
