Go big or go home is the way Stubby’s Pub & Grub (2060 N. Humboldt Ave.) defines mac and cheese. It’s not enough to have a belly-enhancing three-cheese Mornay sauce (fontina, Brie and Sarvecchio Parmesan). For some extra dough (on top of the $11.50 base price), you can add protein such as scallops, chicken breast, a brat or (remember that line about going big?) pork belly. Oooo.
