Eating late is something you're supposed to avoid. But what if you're like, really hungry? What if you've spent the night dancing or bar-hopping or hauling yourself out of Lyft cars? If that's the case, the glowing sign of Arizona Donut Co. is like a beacon in the night, and the lobby — staying well-lit at all hours of the night — seems like it's too good to be true. The 24-hour Tempe doughnut shop has a colorful array behind the glass, allowing you to look and choose your own toasted coconut, apple crumb, blueberry powder, raspberry cream, or double chocolate — among others — to take home or eat on the spot. Arizona Donut Co. also features boba drinks, coffee, anytime sandwich and breakfast items — and 24-hour delivery. Customers get a free doughnut on National Doughnut Day, because of course.
