Pretty good, very close to a 4 star but the burger could've been a bit juicer and flavorful.
Staff was great, recommended various burger types and how they set you up (you direct them to put your add-on's after the burger is cooked (lettuce, tomato, jalapeno, pickled onions, etc. and the sauces). Didn't take too long to come out (got the bacon burger and the flippin burger), and as stated in general it was a good burger but did not 'wow' me. The shakes were sort of the same, pretty darn good but not out of this world.
If I were in the area and hungry I would definitely stop back in, and would recommend the same to anyone else. There are other burger joints in Calgary which I intend to try before I go out of my way to come back.
