Believe the hype. Tasty burgers, great topping options, way above average sides.
Both times I've been here I've had a perfectly cooked (medium, still just a little pink!) burger. They specifically say they don't cook to order (or cook rare to medium) but I've found the patties to be juicy, wonderfully loose (not overworked) and tasty.
I've been split between trying to cram as much deliciousness onto the burger and just having a simple sandwich and letting the meat shine. Both have been great and I'd suggest doubling your visit frequency to enjoy burgers at both ends of the spectrum. (though always get the egg bun!)
Sides have been great across the board, with the only disappointment being the overly greasy smashfries (love the fact that they're shoestring though). Haystack onions are a treat and the mushroom poutine was also great.
I'm not a fan of unsweetened ice-tea, but it's core to the chain's American roots. The beers are decent price at $3.99 (if you don't feel like too much of a dirtbag ordering a beer at a quick-serve place) and the McKay's milkshakes are rock solid delicious.
I'm actually glad that there isn't one near me in the south, or I'd be eating here waaaaaaay to often.
