"an eating-house, establishment where meals may be bought and eaten," 1821, from French restaurant "a restaurant," originally "food that restores," noun use of present participle of restaurer "to restore or refresh," from Old French restorer (see restore).
In 1765 a man by the name of Boulanger, also known as "Champ d'Oiseaux" or "Chantoiseau," opened a shop near the Louvre (on either the rue des Poulies or the rue Bailleul, depending on which authority one chooses to believe). There he sold what he called restaurants or bouillons restaurants—that is, meat-based consommés intended to "restore" a person's strength. Ever since the Middle Ages the word restaurant had been used to describe any of a variety of rich bouillons made with chicken, beef, roots of one sort or another, onions, herbs, and, according to some recipes, spices, crystallized sugar, toasted bread, barley, butter, and even exotic ingredients such as dried rose petals, Damascus grapes, and amber. In order to entice customers into his shop, Boulanger had inscribed on his window a line from the Gospels: "Venite ad me omnes qui stomacho laboratis et ego vos restaurabo." He was not content simply to serve bouillon, however. He also served leg of lamb in white sauce, thereby infringing the monopoly of the caterers' guild. The guild filed suit, which to everyone's astonishment ended in a judgment in favor of Boulanger.

Italian spelling ristorante attested in English by 1925. Middle English had similar words in legal language, such as restaurance "restitution." The railroad restaurant car (1872) was one adapted to afford meals to passengers while travelling.
c. 1200, "thick stick wielded in the hand and used as a weapon," from Old Norse klubba "cudgel" or a similar Scandinavian source (compare Swedish klubba, Danish klubbe), assimilated from Proto-Germanic *klumbon and related to clump (n.). Old English words for this were sagol, cycgel. Specific sense of "bat or staff used in games" is from mid-15c.
The club suit in the deck of cards (1560s) bears the correct name (Spanish basto, Italian bastone), but the pattern adopted on English decks is the French trefoil. Compare Danish klr, Dutch klaver "a club at cards," literally "a clover."
The sense "company of persons organized to meet for social intercourse or to promote some common object" (1660s) apparently evolved from this word from the verbal sense "gather in a club-like mass" (1620s), then, as a noun, "association of people" (1640s).
We now use the word clubbe for a sodality in a tavern. [John Aubrey, 1659]
Admission to membership of clubs is commonly by ballot. Clubs are now an important feature of social life in all large cities, many of them occupying large buildings containing reading-rooms, libraries, restaurants, etc. [Century Dictionary, 1902]
I got a good mind to join a club and beat you over the head with it. [Rufus T. Firefly]
Join the club "become one of a number of people having a common experience" is by 1944. Club soda is by 1881, originally a proprietary name (Cantrell & Cochrane, Dublin). Club car is from 1890, American English, originally one well-appointed and reserved for members of a club run by the railway company; later of any railway car fitted with chairs instead of benches and other amenities (1917). Hence club for "class of fares between first-class and transit" (1978).
The club car is one of the most elaborate developments of the entire Commuter idea. It is a comfortable coach, which is rented to a group of responsible men coming either from a single point or a chain of contiguous points. The railroad charges from $250 to $300 a month for the use of this car in addition to the commutation fares, and the "club" arranges dues to cover this cost and the cost of such attendants and supplies as it may elect to place on its roving house. [Edward Hungerford, "The Modern Railroad," 1911]
Club sandwich recorded by 1899 (said to have been invented at Saratoga Country Club in New York), apparently as a type of sandwich served in clubs, or else because its multiple "decks" reminded people of two-decker club cars on railroads.
