Going skiing in Banff in February and am not familiar with the area. Need dinner suggestions. Prefer something more casual (as nice as we can get into without slacks or sports coat). Willing to try anything as longs as it's good. Have heard the Post Hotel is good but not sure of the attire or price range. Prefer entrees in the $20 to 35 price range. One in the group is a vegetarian but isn't too picky about his food.
