Dairy Mart in carrollton has actually switched it's name to Circle K now. They've always been a great place to shop with great customer service, and nothing has changed about that since the name has changed. The store has gotten a face lift, inside and out, even a new restaurant, Noble Romans. I haven't tried the restaurant yet, but it smells wonderful in there. The store is always clean and orderly, and the customers are always treated courteously.
