In this era of mass marketing, Nebraska, in many ways, has taken an isolationist stance when it comes to food and drink. It may not be artisanal/Alice Waters local, but at least it's something to call their own (and to share slightly with Iowa and a couple other midwestern states). As mentioned previously, there's the love of Red Beers (cheap American beer and tomato juice). We loved ours at Lee's Chicken, this great old road house featuring live organ music every night (we requested "Home on the Range" as an homage to Gramps).
And then there's Runza, the fast food chain that serves up these German-Russian beef pockets. In a move of great local pride, they've added the classic Miller & Paine cinnamon roll to the menu. Miller & Paine was one of Lincoln's main family owned department stores that served these sugary confections (they taste like cinnamon toast due to the heavy quantity of white sugar) at its lunch counter. Dillards bought them out years ago and that '50s legacy sort of died out, though the cinnamon rolls lived on through Braeda bakery. (Interestingly, my mom craved the Runza cheeseburgers when she was pregnant with me, so I gravitate to those, while Port loves the old standard - with cheese).
