You can get like, 2 burgs and a drink for the equivalent of $1.50 near here. They're not too big but they taste decent enough. There's this one place that sells these great Vegas-styled American-sized chilicheese burgers for around 3 bucks though.
As mouth-wateringly delicious those chilicheeses are, they're just a tad too pricey for my taste. The local fast-food place's big burgers are no better in this department.
White Castle's Sliders Burger. http://www.whitecastle.com/ Just add another nine and Iowa would be right at home. Though she's have to go to Minnesota to get some from Iowa. Be easier to stop in California from her Pacific tour with the shipgirls.
