Unimpressed. Basically you're paying gourmet burger joint prices for quality that doesn't even match Harvey's.
The Soul Burger, aka veggie burger, is $7.79 with fries and a drink. I upgraded the fries to a Poutine for an extra $2. The veggie burger was a thin, bland patty with hardly any toppings. I asked for extra pickles and still only got about 3 tiny slices of pickle and they were the cross-sectional slices rather than the larger lengthwise slices. Lame.
The fries were undercooked and the gravy was bad. At least they use proper cheese curds in the poutine.
Some of my coworkers got the meat burgers and they were equally unimpressive. Thin, tasteless, pre-formed patties.
If you're looking for a quick and cheap burger go to Harvey's. For a proper gourmet burger go to Craft Burger or one of the many other gourmet burger joints in town. Don't bother with Hero Burger. It's the worst of both worlds.
