The departure of a Sleepy's mattress store and renovations for an incoming urgent-care center exposed these traceries of the famed kosher dairy restaurant (est. 1905, moved here 1918, closed 2004). What looks like lettering, however, may never have been visible during the restaurant's long run. More likely this is the silhouette, highlighted by subsequent touch-up paint jobs, of the boxy metal trays that held the letters of Ratner's neon sign.
See also this menu, from 1987, and tell me you wouldn't like a little nesselrode pie.
