While en route back to Canada from Wyoming, stopping in Bozeman, Montana, I manged to come across Montana Wheat Company and Bakery located at Three Forks. This restaurant is just off the interstate; if headed North towards Helena you will drive right past it.
The exterior of the restaurant is unique outside with the silos attached (incorporated into the building). I built my own sandwich (or you can chose one of their already built sandwiches), and also picked up an almond bear claw (YUM!), cookie, and almond cinnamon roll; all of which are extremely delicious.
This place is extremely clean, very fast (had four ladies taking orders), all of which were very helpful.. Also, you can buy their wheat, flour, pancake mixes, grain blends directly from them; Neat!
