If you are looking to find some beers you don't normally see served in pubs in Calgary I recommend checking out LDV Pizza Bar in Bridgeland.
These lists have changed/grown since they were posted to the website, quite a few more bottles in the selection now, but this gives you an idea. I'm currently on a La Chouffe kick.
