I have attended most of Earl's locations in Alberta and Saskatchewan. The 16th Ave location fits in well. Well decorated, very good service and yummy food. Parking can be a little weird, but typically it's fine, especially once you get the hang of how this location's setup.
My biggest point of confusion with Earl's in general remains a lacking support for Gluten-free options. They do have SOME basic accommodation. I wish they had GF buns at least for their burgers, but not so. My wife and I both have developed Gluten issues and our needs often dictate where the group goes, so good GF options can kind of have a large impact. Anyways, Earl's handles us well enough.
