Let’s start this out by getting something cleared up: there is no one sandwich known as a “hamburger.” Hamburgers have types; the hamburgers you get at different places aren’t really even the same. They range from your basic fast food burger (McDonalds, Burger King, …), to big two-handed thick burgers (Cheeburger Cheeburger, Fuddruckers, and, for you Arizonans, The Chuck Box), to specialty burgers (like the cheese-filled Jucy Lucy of Matt’s Bar in Minneapolis). And there’s little comparing burgers from one category to another. Indeed, one of these categories is the “slider”, the diminutive little burger fried on a bed of onions served on a little poofy roll. Midwestern folks can get them at White Castle, while Southerners get these at Krystal. And, for some odd reason, there are a lot of places in the Detroit Metro area that really took the White Castle concept to heart, opening similar burger joints in similar-looking buildings, with similar sliders.
