My daughters favorite restaurant in Bismarck. We went there twice on a recent trip, once for dinner and once for breakfast. It is one of the quaintest place I've been in. A narrow corridor of booths and the front room packed with tables. Hope you don't have a large family.
I guess what struck me about this place was its friendliness. Now North Dakota is a friendly state, but here you felt like the staff were happy to be there. There was a real sense of camaraderie and teamwork.
