I should start this off by saying that my review is slightly biased. This is because I (very briefly) worked in this shop. And I've seen behind the scenes here.
Needless to say, the selection is great. Prices aren't bad and the place generally has a nice small town feel.
They're constantly producing in the back, but conditions back there could be better. Not enough access to handwashing stuff, not a lot of handwashing happening and employees are not provided with (or expected to use) gloves when handling donuts. And they are all iced and decorated by hand.
So there's a "Eat art your own risk" kind of motto when you eat out, this place isn't exactly out of the ordinary but I prefer to go where I don't know what it's like in the back.
