The interior space design of the restaurant is the soul of the restaurant. On the basis of following the design principle of dining space, dining space should be limited to a certain extent. The forms of the entities enclosing the space can be ever-changing and varied, but they can all be classified into two categories, namely, horizontal entities (such as floors and ceilings) and vertical entities (such as columns, partitions, furniture, etc.). There are also many combinations of dining space.
