I went to the one in Medicine Hat when i was there for work and i must say that it was one of the best burgers i've ever had. It was a fairly big burger, for me at least, and i got to choose whatever toppings and condiments i wanted. Also the cajun fried were very good as well.
Granted i haven't been to those other burger chains like White Castle, In N Out etc. so i can't compare with them. It was a little pricier than your McDonalds or Wendy's but definitely worth a try!
