Proper signage is absolutely vital in any restaurant for many reasons. Some signs, such as entrance, exit, no smoking and handicap signs, are requirements for all public buildings in order to meet public health and safety codes. Other signs quickly and effectively mark bathrooms, in-store rules and areas in which customer presence is not permissible. Update International has a sign for nearly every situation. Its “Entrance” sign (S39-10BK) clearly marks which doors may be used for entering a building.
