Oyster-house

An oyster bar, also known as an oyster saloon, oyster house or a raw bar, is a restaurant specializing in serving oysters, or a section of a restaurant which serves oysters buffet-style. In France, the oyster bar is known as bar à huîtres. Oysters have been consumed since ancient times and were common tavern food in Europe, but the oyster bar as a distinct restaurant began making an appearance in the 18th century.

Human consumption of oysters goes back to the ancient Greeks and Chinese. Oyster consumption in Europe was confined to the wealthy until the mid-17th century, and by the 18th century even the poor were consuming them. Sources vary as to when the first oyster bar was created. One source claims that Sinclair's, a pub in Manchester, England, is the United Kingdom's oldest oyster bar. It opened in 1738. London's oldest restaurant, Rules, also began business as an oyster bar. It opened in 1798.

In North America, Native Americans on both coasts ate oysters in large quantities, as did colonists from Europe. Unlike in Europe, oyster consumption in North America after colonization by Europeans was never confined to class, and oysters were commonly served in taverns. During the early 19th century, express wagons filled with oysters crossed the Allegheny Mountains to reach the American Midwest. The oldest oyster bar in the United States is Union Oyster House in Boston, which opened in 1826. It features oyster shucking in front of the customer, and patrons may make their own oyster sauces from condiments on the tables. It has served as a model for many oyster bars in the United States.

By 1850, nearly every major town in North America had oyster bar, oyster cellar, oyster parlor, or oyster saloon—almost always located in the basement of the establishment (where keeping ice was easier). Oysters and bars often went hand-in-hand in the United States, because oysters were seen as a cheap food to serve alongside beer and liquor.

By the late 1880s, an "oyster craze" had swept the United States, and oyster bars were prominent gathering places in Boston, Chicago, Cincinnati, Denver, Louisville, New York City, and St. Louis. An 1881 U.S. government fisheries study counted 379 oyster houses in the Philadelphia city directory alone, a figure explicitly not including oyster consumption at hotels or other saloons. In 1892, the Pittsburgh Dispatch estimated the annual consumption (in terms of individual oysers) for London at one billion, and the United States as a whole at twelve billion oysters.
