White Tower

White Tower - I think I actually remember these!

White on white doesn't really work, so let's throw a little color in the background. W (do you see it?) + tower = White Tower.

A little bit about White Tower:
(from Wikipedia)

White Tower Hamburgers was founded in 1926 in Milwaukee, Wisconsin, and with its similar white fortress-like structure, is considered an imitator of White Castle. The chain was successful and expanded to other cities, including Chicago, Indianapolis, Cleveland, Detroit, Philadelphia, Pittsburgh, New York City, Albany, Boston and as far south as Richmond, Virginia. During the Great Depression, White Tower sold hamburgers for five cents.

The whiteness of the restaurant was meant among other things to evoke the notion of hygienic conditions, and the chain had staff dressed as nurses, dubbed the "Towerettes," to help make this argument.
