Tracing back the origin, this kind of theme restaurant has been popular in Britain since the 1990s. Yang Jianfei, a professor at the Cultural Industry Research Institute of Communication University of China, said, "As an old capitalist country, the British economy experienced a downward trend in the 1990s. At that time, the strategy of saving the national economy with innovative thinking was proposed." According to the "Theme Restaurant Industry Survey Report" made by the British Mintel International Group in March 2001, the first theme restaurant (HardRockCafé) was opened in London in 1971, and in the 1990s, the theme restaurant in the United Kingdom developed rapidly, with turnover accounting for 7% of the catering industry. This type of restaurant to new, strange, special concept to attract the 15 to 35-year-old crowd patronage, the theme around sports, music, film and television.

In the 1990s, these restaurants began to flow into China's Shenzhen, Hangzhou and Chengdu, and have gradually diversified their themes while being favored by younger groups. The idea of introducing a toilet into the restaurant came from a toilet exhibited in the middle of an art museum in Paris during a visit a few years ago. The toilet was the one that French artist Duchamp sent to the New York Society of Independent Artists in 1917 for an exhibition titled "The Fountain". Duchamp himself explained the significance of "The Fountain" in an essay: "It doesn't matter who made this thing, the point is to choose this ordinary thing in life, put it in a new place, give it a new name and a new angle of view, and its original role disappears.

American scholar H.G. Block, in his book Aesthetics: The Philosophy of Modern Art, commented:

A urinal placed in a bedroom does not constitute any commentary, while Duchamp's urinal is a kind of authentic art commentary. It is a commentary on the traditional split between art and life, challenging and refuting the traditional view, while claiming to be another kind of art against it.

Naturally, Mr. Lin can't compete with Duchamp, who aims to make money by exploiting people's innate curiosity and the modern city's pursuit of excitement and style, but in objective terms, like The Fountain, the toilet-themed restaurant offers a new way of looking at toilets, and challenges and refutes traditional views of people's habits and lives. In fact, decorating a restaurant like a toilet, serving food in containers shaped like urinals, serving ice cream shaped like poop, and letting diners eat while sitting on flush toilets is nothing more than a similar shape, isn't it? And, as Duchamp noted, when these toiletries are placed in a new environment, such as a restaurant, their original purpose disappears. Yet it's a given that toilet-themed restaurants, at least in China, cause a lot of offense.

First of all, human beings have an innate aversion to their own excrement -- especially feces -- because of its bad odor. The halo that hangs over a saint's head must immediately dissipate at the thought that even the saints we worship have to poop and pee; and the West is no exception to this rule, claiming that Christ could eat and drink, but not defecate. Although the ancient Chinese philosophers talk about Qi things, but in the ordinary people, exactly can not be so open-minded and relieved, after all, still think that the upper body used for eating and drinking is more noble than the lower body used for defecation; so our food culture is very developed, but the toilet culture is very backward. As the toilet, jokingly called the place of reincarnation of grains by Mr. Piggy, is a special place used by civilized people to solve the problem of defecation, naturally, it establishes a deep-rooted association with unpleasant excreta. Secondly, in the eyes of ordinary people, toilet is synonymous with dirty, messy and smelly. Because China's toilets, especially public **** toilet, often due to economic backwardness or national quality can not keep up with the reason, the sanitary conditions are very poor, I'm afraid that even the best appetite to think of China's toilets of that kind of scene can not eat. Therefore, the toilet theme restaurant criticized by some of our countrymen, in a sense, reflects the dirty, messy, smelly condition of our toilets.

Writer Mr. He Fan said in his column in the United Daily News that toilets are a benchmark for assessing the standard of civilization. In today's developed countries, toilets are seen as a convenient place for cleanliness, hygiene, and spiritual adjustment, and accordingly, their architecture is exquisite, giving people a sense of comfort and beauty, and even if one eats in such toilets, I believe that it is difficult to find anything that would cause one to feel disgusted.
