Donut Bar is located a block from Fremont Street Experience and their donuts are simply amazing.
I've tried to come mid morning but every time they were sold out. I suggest you come as soon as they open to get exactly what you want because they do sell fast.
I tried the sprinkled Oreo stuffed donut and my oh my was it good. They have a ton of selections and I highly recommend them.
I defiantly see why they were voted the best donuts in Vegas.
