Nice clean store. Friendly staff, good selection of merchandise.
Very clean, staff is very friendly and helpful. They have many items like most convenience stores. They also cary regular, unleaded, premium gas along with diesel. Credit card or cash is acceptable. And public restrooms.a great place.
If you have a patron account you get money back on gas purchases.
Clean and friendly service. They sell Pride of Dakota kuchen that is to die for in the frozen section. Car wash isn't half bad either.
