A ladies' night is a promotional event, often at a bar or nightclub, where female patrons pay less than male patrons for the cover charge or drinks. In the United States, state courts in California, Maryland, Pennsylvania and Wisconsin have ruled that ladies' night discounts are unlawful gender-based price discrimination under state or local statutes. However, courts in Illinois, Minnesota, and Washington have rejected a variety of challenges to such discounts.
