I would have to say that Darling Donuts has the best donuts I've tasted in AZ! They far out beat Bosa, Dunkin, Rainbow, and any grocery store bakery. They're the best in town! Not only are their prices very reasonable, they even offer great customer incentives! You need to try them out because:
1) great and yummy donuts!
2) new customers get a free donut
3) customers receive a stamp card that can be used to attain a free dozen of donuts
4) friendly and polite customer service
4) need I say more....the donuts are yummy!
