the decoration design and facade decoration of catering stores are very important. Generally, there are a large number of commercial stores, and there are many kinds of business services. Because of the different environments in the city, the standards of the scale and facilities are also different. Therefore, it is impossible to stipulate a unified standard for the content and specific requirements of the store decoration design. The facade modeling of catering stores should be basically unified with the form and style of surrounding buildings; The relationship between wall division and building volume, proportion and elevation scale is more appropriate; The combination of various formal beauty factors in restaurant storefront decoration should be focused, clear from master to slave, and rhythmic and rhythmic in comparison with changes in storefront decoration. The population and window of a restaurant store are the key parts of the store, and its location, size and layout should be determined according to the specific conditions such as the plane form of the store, the location environment and the width of the store. The store population and window are suitable for the location scale of plaque, advertisement, sign and store emblem, and the store decoration has obvious recognition and guidance. ?
