We have tried to visit this store 3 times in the past week, due to the good reviews on Yelp.
The first time we visited on a Tuesday around 3PM, on arrival the doors were locked and a sign read "Sold out, no more donuts".
A couple of days later we wanted to try again, so called the store at around 12PM to be told they only have a few left. We didn't want to drive over again only to be disappointed.
Our third and final time, third time lucky you may be anticipating, we went to the store at 1PM on a Saturday and the cabinets were empty. There were not even enough donuts to fill a single tray, in a large cabinet with many trays. We left the store without purchase as the only remaining were nothing special.
In conclusion, we will not be revisiting the store and would advise other customers to definitely call ahead if you are traveling any distance to try this place. Perhaps the store should figure out how to supply their donuts better, or change their opening hours to reflect when they actually have stock.
