The first time I went to this place I was really impressed. Great burgers with real or processed cheese - you can choose! Also lots of free toppings like sauteed onions, mushrooms, pickles, and all the other burger stuff. Thin meat, "smashed" so it is flavorful and yummy.
Great sides too: Pickle chips, mushroom poutine, smash sweet potato fries (tossed in olive oil and garlic) and even salads. Cheap beer - $3.99 Stella in a chilled glass!
However after I went back 3-4 more times the last few have been bad. The fries have been sitting under a heat lamp far too long, the burgers have been really greasy, and the service not too spectacular. I took my younger brother here on a Wednesday night and it was an hour before closing and the server came and took our plates and my half full soda glass that I was still drinking, then vacuumed our table intruding into our conversations.
So I'll probably still be back; but this is a US franchise that is just new to Calgary. Give it a year and it will be nothing to write home about.
