Like many other fast food restaurants, Dairy Queen has a 'secret menu' of items just waiting for you to order from it. Rumor has it that each DQ establishment has a book that includes all old item recipes that are no longer on the traditional menu. So if you have a hankering for a Blizzard of the Month that is no longer available, ask for it anyway. The same goes for sundaes or other seasonal items. But, if you're not exactly finding what you want on this secret menu items list you might want to check out the Sonic hidden menu items or even the Five Guys off menu items.
