Mudka's Meat Hut is a local diner from The Emperor's New Groove franchise. The restaurant primarily sells meat products, but also sells other food like potatoes and salad. The man figure outside the place is a possible parody of the mascot for the Big Boy restaurants.
Kuzco and Pacha stop here to hide from Yzma and Kronk, unaware they they have also stopped there for a meal. Because the restaurant doesn't allow llamas inside, Kuzco is disguised in drag and pretends to be Pacha's wife on their honeymoon. There, the frustrated cook has Kronk take over the cooking while Yzma gets suspicious about the "married couple" that are Kuzco and Pacha in disguise.
Kronk is now the head chef and delivery boy at the diner. At the climax of the story, Papi shows up there to see if Kronk is married. However, many of Kronk's friends end up pretending to be "Mrs. Kronk" before the cheese Kronk had been cooking blows up and the restaurant becomes covered in melted cheese.
