I've been working down the burger list lately. Here is my tally up;
Killer Burger: Killer, Epic, Black Molly and Barnyard. All were excellent but the Black Molly was my least favorite. Epic was my favorite... Pulled pork, bacon and burger!
Tilt: Classic single/double with bacon, Big Tilt, Bacon gravy fries. The big tilt was delicious but expensive for having no sides. I now only go during their happy hour special and get a classic. The fries are two for one during happy hour as well.
Lardo's: Double Burger and dirty fries. It has porkstrami and the meat is very good. Burger was extremely tasty, fries were ok but they got cold very quick which was a bad combo for having so many roasted peppers on top. They were tasty when hot though.
The Original: Doughnut burger sliders and poutine. I would do this again any time I was in the area. It was probably my second favorite meat of all the burgers and the weird glazed doughnut contrast was pretty exciting. Also... Poutine. You might think this was awesome if you knew what it was.
Bar Bar: Classic burger. It was decent and the most affordable of all the burgers mentioned (Except some Happy Hour specials). My buddy had one of their seasonal specials that had bacon on it and shared a bite of it. Their bacon was probably the best of all, so if you get a burger there, get the bacon.
Best bang for the buck: Killer. Even with bottomless fries, you'll be full before you even ask for a second helping. Even my 300# buddy skipped on seconds. During happy hour makes it the best option by far. Bar Bar was a decent value, but on the burgers worth eating you'll end up paying for it.
However, if you go during the happy hour and are bringing several people to help with the food, Tilt is a great place because the fries can feed 2-3 people each as a side.
I have a few more burger places on my list but I've had some delays on getting my ass out to them.
