All you can eat

Meaning

A restaurant advertising slogan (usually followed by a price).

Origin

It will probably come as no surprise that this is an American phrase. 'All-you-can-eat' restaurants spread throughout the USA during the depression years of the 1930s, when diners' hunger was often bigger than their budget. The deal with such restaurants is an unlimited amount of food, usually arranged as a self-service buffet and usually pretty low quality, for a fixed price - also low. 'All-you-can-eat for 50 cents' was a typical early slogan. That's the line in what is the earliest printed record of the phrase that I've yet found. This is from one of Harrison Cady's Peter Rabbit cartoons, published in the Oakland Tribune in April 1933.

All you can eat is still a popular form of dining and has now spread to all continents. In more recent years the restaurants have moved up-market somewhat. Minimum price is no longer the only factor and you aren't now likely to eat all you can for 50 cents.

In the late 20th century the phrase began to be used in an allusory manner, that is, not limited to references to food. An example of that is from a 1994 edition of Internet World:

"Costs of typically $1-2 per hour or $10-$30 per month for 'all you can eat' use of reachable free-for-access Internet service."
