A fried-brain sandwich is a sandwich that is generally served as sliced calves' brains on sliced bread. Thinly sliced fried slabs on white toast became ubiquitous on menus in St. Louis, Missouri, after the rise of the city's stockyards in the late 1880s, although demand there has so dwindled that only a handful of restaurants still offer them. However, they remain popular in the Ohio River valley, where they are served heavily battered on hamburger buns. In Evansville, Indiana, they are still offered at several "mom and pop" eateries, specifically the Hilltop Inn, and remain a favorite dish, featured at the city's annual West Side Nut Club Fall Festival. Kissner's, a traditional workman's taproom in Defiance, Ohio, has offered a brain sandwich since 1928.
