We visiting one night in the off season from Calgary and enjoyed a amazing dinner-scallop salad/brie to start followed by the best Bison we have had anywhere. Portions are very generous and Wine was reasonable. Our dinner and breakfast was included with our nights accommodation.
It was very cold when we visited but the fireplace and heater was able to keep our cabin cosy.The cabins were built in 1923 and although rustic are charming- I would rate the cabins as good and the restaurant as excellent therefore the overall rating of very good.
I would recommend visiting Storm mountain lodge - you can make reservations just for dinner , just keep in mind that it is about 1/2 an hour drive from Banff.
