I'm going to say it, best burger in Calgary without having to leave downtown. Downtown is a sea of corporate restaurants frequented by sales guys with expense accounts who don't know how to procure a fine burger with fresh ingredients. Or you can find a Wendy's in every second building. Holy Grill's downtown location (is mysterious to find in the +15 network) but well worth the lunch time hunt.
Awesome people, great service, awesome sides, and I like the open kitchen to see how it all goes down.
