"Adam and Eve” in diner lingo means an order of two eggs. The term “Adam and Eve” has been cited in print since at least 1891 and might have originated in an eating establishment on New York’s Bowery (see the 1899 citation below).
“Adam and Eve on a raft” (two poached eggs on toast) has been cited in print since at least 1892. “Adam and Eve on a raft & (ship)wreck ‘em” (two scrambled eggs on toast) has also been cited in print since at least 1892.
Wikipedia: Diner lingo
Diner lingo is a kind of American verbal slang used by cooks and chefs in diners and diner-style restaurants, and by the waitresses to communicate their orders to the cooks. It is virtually unknown outside the US.
The origin of the lingo is unknown, but there is evidence suggesting it may have been used by waiters as early as the 1870s and 1880s. Many of the terms used are lighthearted and tongue-in-cheek and some are a bit racy or ribald, but are helpful mnemonic devices for short-order cooks and staff.
