We can recommend the one near the Premium Outlet mall and Dolly's Dixie Stampede. It has lots of great groceries including all the stuff you want if you hire a villa (like the sunday roasting joint)

brilliant biscuits range including lots of multipacks cereals, fruit and vegetable a fantastic bakery section ,and plenty of toiletries and beer/wine/spirits,lots of bottled water fresh juices and dilute squash, even the freezer section has lots of ready meals ideal for the microwave.I think they had papers and magazines too
