I used this msg board for my recent 2 week trip to this most beautiful part of the world. This is what is worth a look and this is what is not worth your time:
Banff- ( Worthwhile) : Silver Dragon for Chinese, Typhoon for Thai, Sugyaki for Japanese, Evelyns for coffee and cheap lunch or breakfast.
( Most Dissapointing)- Coyotes - too expensive, food too salty - not sure what all the rage is about.
Canmore - Stop a Vebella Meats - yummy for the bbq and for sandwiches and cheese.
Lake Louise - Post House was closed until December - other then that - pack a lunch from home .
