Situated in the Windy City’s River North neighborhood, The Doughnut Vault opens at 8:30 am each day from Tuesday through Friday and 9:30 am on Saturday mornings. Patrons are given good incentive to get there promptly, however, because the store closes its doors for the day as soon as the last doughnut is sold — often within an hour, PSFK reports. Some 600 pastries are reportedly sold by The Doughnut Vault each day.
