The Mezzanine (1988) is the first novel by Nicholson Baker, about what goes through a man's mind during a modern lunch break.
On the surface, the novel deals with a man's lunchtime trip up an escalator in the mezzanine of the office building where he works (a building based on Baker's recollections of Rochester's Midtown Plaza). In reality, it describes the thoughts that run through a person's mind in any given few moments, and the ideas that might result if he or she were given the time to think these thoughts through to their conclusions. The Mezzanine does this through the extensive use of footnotes—some of them comprising the bulk of the page—as the narrator travels through his own mind and past. The footnotes are quite detailed and sometimes diverge into multiple levels of abstraction. Near the end of the book, there is a multi-page footnote on the subject of footnotes themselves.
The Mezzanine is a plotless, stream-of-consciousness examination that greatly details the lunch-hour activities of young office worker Howie, whose simple lunch (popcorn, hot dog, cookie and milk) and purchase of a new pair of shoelaces are contrasted with his reading of a paperback edition of Marcus Aurelius's Meditations. Baker's digressive novel, partly composed of extensive footnotes of up to several pages, follows Howie's contemplations of a variety of everyday concepts, such as how paper milk cartons replaced glass milk bottles, the miracle of perforation, and the buoyant nature of plastic straws; and everyday objects such as vending machines, paper towel dispensers and popcorn poppers.
I'm on the mezzanine floor
Never been here before no no
It's a lonely place
But a house full of grace
And I'll get to heaven
Yes, I'll get to heaven
I'm at this bolted door, but I'm
Coming through without permission
If I go they say I'm wrong
If I stay there'll be no song
And I'll get to heaven
