My partner and I enjoyed a fabulous meal at the Bison. The waitress was very attentive and friendly and explained parts of the menu to us non-Canadians who are not familiar with local cuisine. We enjoyed a great bottle of red wine from the Prospect winery and it was fairly reasonably priced too. All the food is sourced from Alberta and British Columbia which added to the charm for us, I can heartily reccomend the Bison Steak.
We will look to book a table again next time we are in Banff
