No person under 21 years of age is allowed on public premises. There are two classes of public premises:
As to on-sale general and on-sale beer and wine licenses, this means premises maintained and operated for the sale and service of alcoholic beverages to the public for consumption on the premises, and in which food is not sold or served to the public as in a bona fide eating place, although food products may be sold or served incidentally to the sale or service of alcoholic beverages.
