no minors allowed

A policy excluding minors indicates that persons below legal adult age (usually 18-21 years) are barred from entering the premises, at least during periods of its usage. This applies often to places for gambling, drinking, adult entertainment, and sexual services, as well as to secure areas such as military installations and protected research facilities.

The age boundary is the legal adult age applicable to the policy. The specific number must therefore come from that policy's setting rather than a universal age in the category.

No children allowed uses a younger age threshold around 10 to 13. The two restrictions can exclude different age groups even when imposed for similar reasons.
