Mos Burger has a special promotion tie in right now with Mister Doughnuts. The created a “special” burger as a tribute to the doughnut king of Japan. It’s the doughnut burger!
Basically it’s a clever way to get you to spend the same amount of money to get less meat. You can’t even see the doughnut hole when it’s all put together. Mister Doughnuts has returned the favor and made some hamburger shaped doughnuts using chocolate instead of beef. You can see them in the picture below.
They even have doughnuts that look like french fries.
