I have been eating breakfast in Miles City once a week for over 2 years. I went to the 600 a couple of times but it seemed kind of greasy and the sausage gravy was almost inedible. As a result, 4-B's became a regular stop until the under-cooked hash browns became too much to digest. Now it is Gallagher's on a weekly basis. There a person can find both great service and an edible breakfast.
On kind of a side note, I finally have begun to order my eggs, scrambled. At least when scrambled, my eggs are consistant, meaning I don't have to wonder if the cook and I are on the same wavelength when I order eggs any other way.
