It's in a strip mall so you will have to look for it, but it's worth the look.
It's a very simple store, not fussy at all. Everything is reasonably priced nothing looked over $2, which I have found, especially when you begin to add toppings.
There strawberry with m&ms was my favorite donut plus the donut holes are amazing and only $2!!! Love this place!! I will be back anytime I'm in Phoenix
