Stuffed to the heavens with cheddar cheese and piles on piles of hot dogs, this beer is a Blue Box dream. Waves of nostalgia come crashing with all the best memories from the Blue Box dinners of yesteryears. Mac-PRRRT-a-Roni is not a macaroni and cheese with hotdog ESSENCED beer. It is 100% Mac-Dog-a-Roni in liquid, alcoholic form.
