I've gone here twice. First time I ordered the steak, and it was super mediocre. However, just went there today and had their burger, and was completely blown away. Totally awesome.
They have all kinds of ingredients (and it is for sure sauerkraut not slaw) which I love. Very sloppy burger but extremely tasty.
I will definitely be going here again and getting the burger. Next time I'll try a poutine too.
