Been here a couple of times, kinda off the main road from Rainbow.
I cant speak how the morning rush is here since I only come as a late night snack after work after the hours from 6-8pm.
What I can say, is at this time, the place is very clean, not busy at all. Im usually 1 of 2 people here. They ALWAYS provide fresh off the line glazed donuts!! SOOOOO DELICIOUS
My favorite person here is Dawn, She always has a smile on her face and was so helpful and jolly.
HINT: Download the Krispy Kreme app and every year on your bday they send you a FREE donut (any donut) and small coffee or soda!
