The Alcohol Act does not forbid minors from staying in the licensed premises. However, the licence holder may set an age limit for the premises. The Alcohol Act includes a provision on auditorium areas restricted to those who are 18 or older. Sports, music or comparable auditorium areas may be approved as a serving area if access is limited to persons aged 18 or more. No minors may be permitted to enter such areas when alcohol is served.
