Home of the tiny slider with enormous taste.
Sliders, belly-bombers, gut-busters, whities, or whatever nickname you choose: White Castle serves burgers unlike those found anywhere else. The small (about 3 inches), square-shaped, fried morsels topped with onions are legendary. With every White Castle in the Chicagoland area open 24 hours, it's easy to follow Harold and Kumar's example and fulfill your late-night craving.
