the.com/club sandwich

means A doubled-up sandwich — usually turkey or chicken, bacon, lettuce, and tomato — stacked between three slices of toast and cut into triangles, held together with frilly toothpicks.

from Most food historians trace it to late-19th-century American social clubs — specifically gambling and gentlemen's clubs, where kitchens served hearty late-night fare to members. The Saratoga Club House in New York is the name most often attached to the story, though hard documentation is thin and the exact 'first' version is disputed. What's solid: the name 'club' simply reflects its origin in club dining rooms, not any clever wordplay — the sandwich earned its reputation for excess all on its own.
