After 2 years in Phoenix, I finally found a donut place which churns out consistently high-quality simple donuts. Located in an unpretentious building with super-friendly and efficient staff, my average wait time was less than 3 minutes over the past 6 (yes, 6) visits.
The Good:
Great variety of donuts.
The simpler ones are the best (Chocolate & Mapel Glazed, Old Fashioned & Cruller).
Inexpensive (paid $3.xx for a bagel w/ cream cheese + 2 long johns).
Staff is friendly yet efficient.
The Not-so-good:
The more complex donuts tend to be sweeter (understandably so).
Overall:
Great place, excellent donuts, superb service. Stay away from the jelly-filled, super crazy donuts and go for the simple, fluffy and fresh glazed donuts. Your taste buds (and to some extent, your waistline) will thank you for it. :).
