Great donut shop (Thank you local yelper Philip T for the review!) serving unique donuts. If you aren't looking for it you probably wont know it is there as Ace Donuts is in a strip mall with very little signage.
I liked their cronuts (bacon cronut was flaky, sweet, savory goodness). I am not a huge fan of cream filled...but even they were good. Try the key lime filled, the apple filled etc. I hear the apple fritter I chose was also fantastic.
Prices are a little high and it is not the most glamorous spot (almost dreary inside)....definitely a take-out to go kinda place.
If your in spring valley...check em out!
