This National location is pretty consistent to the three others. I visited when they opened during Stampede - really nice to have a big beer garden in downtown Calgary again. They only had canned beer at the time but that's since been resolved.
When I returned a few weeks later, I had made a group reservation for the patio. They made an error on our reservation and had us at the Westhills location, so we were forced to sit inside. It was somewhat disappointing but otherwise a good time was had by all.
