Of course, there are western-style restaurants that don't have cold tables, but rely on service staff to deliver meals. Western-style restaurants pay special attention to the privacy of dining units, and there are generally the following methods to create privacy:

(1) Raising the ground and lowering the ceiling, which creates a weak degree of privacy, but it is easier to feel the limited area.

(2) Using the backrest of the sofa seat to form an obvious dining unit, this U-shaped sofa seat is often combined with the backrest seat, which is one of the unique seating arrangements in western restaurants.
