Clubs, Bars:
The age of entry for places of entertainment, dancing halls, discos and dance theaters (the latter is excluded if the dance on stage is viewed by a sitting audience) is 16 years, so that persons younger than 15 may not enter. In addition, persons aged 16 and up must identify themselves to the owner.
In the case of establishments (bars, etc.) which have a license to sell wine and alcohol/spirits, minors may not be present in or loiter outside of such places (Subsidiary Legislation 10/09 and Cap. 10, § 185A).
Children of any age may be present in restaurants when accompanied by their parents or by a guardian (as the case may be).
Harmful Places:
There is no official definition of such places.
Places for gambling:
In the regulations for amusement machines (the Amusement Machines (Restriction) Regulations), there are no age limits for the use of such machines, so that children are not prohibited from seeking out public gambling halls and using the said machines. However, it is important to consider the definition of amusement machines. Such machines are defined as "any type of machine which is operated by the insertion of money or any amusement machine tokens and where a successful player neither receives nor is offered any benefit other than the opportunity, if any, afforded by the automatic action of the machine to play the game again without the insertion or other money or amusement machine tokens, including machines known by the names 'kiddie ride machines,' music boxes and public 'soccer tables.'"
