Not sure how far down south their gas stations go. The only one that I know of in North Dakota is in Fargo. Never experienced their donuts before until we went to Kansas last year. Threw down a whole dozen between three of us and wished I had bought two dozen. Never had their pizza but I hear that is fantastic as well.
We leave for South Dakota in about an hour so I will be filling my face with their donuts on Sunday morning as that’s Vinny Quack‘s birthday. May even sample the pizza!
Anyways if you ever get a chance, give their donuts or other pastries a try! I don’t think you will be disappointed!!
