I'd like to rate it 4 stars, but that would be over-reaching: 2.5 is closer!
After talking to the owner - an older gentleman who'd been owner for many years - and feeling hyped to try one of their featured burgers, I did and can only rate it 3.0 tops. History cannot make up for what is missing in the food!
The burger was good, the fries a nice sidekick, and the garnish ordinary, and boring: this burger with special meat was not at all outstanding re. flavours, etc. In fact, after being assured it was the best burger in Canada - as sprayed all over the outside window - I had to conclude his assessment is highly inflated, for it was far from that!
The interior is clean but with no flair for decor or ambiance. In fact, it very much is a metaphor for the burger meal: just plain, plain, plain.
If you crave a better burger in the general vicinity, either check out The Rock on 17th past 14th Street, or Naina's at the other end of 17th near MacLeod Trail. They and perhaps others nearby are much closer to what I used to bbq at home...
