First of all, when it comes to theme restaurants, people may easily associate it with special restaurants. However, there is still a big difference between the two. Because the theme restaurant is a special kind of restaurant to some extent. The essential element of theme restaurants is to have their own characteristics, that is, the capital for the survival and development of theme restaurants needs to meet the characteristics of "personalization". However, specialty restaurants are not necessarily theme restaurants. For example, there are many special restaurants in the catering market, but in a strict sense, some of these restaurants cannot be called theme restaurants. Because theme restaurants are distinctive dishes, we should also pay great attention to the in-depth development of theme culture and the creation of corresponding environment, so as to help the environment highlight its own theme characteristics. Furthermore, the distinct theme pursuit can give consumers a very refreshing visual experience, which can not only improve consumers' desire for consumption, but also enable consumers to enjoy the ultimate spiritual level, thus improving the spatial environment atmosphere of theme restaurants. If the restaurant only refers to its own space, it is actually relatively plain and simple. The integration of the theme gives the whole dining space a soul and makes the whole restaurant look particularly beautiful and vivid. In the decoration design of themed restaurants, a distinctive theme can often enhance the artistic beauty of the whole space and make it an important spiritual wealth of restaurants, thus guiding and changing people's original aesthetic concepts and deepening their understanding of the theme of restaurant decoration style.
