An appeals court rejected a case brought to close down ladies nights in New York:
The Manhattan-based Second Court of Appeals rejected a claim by Den Hollander, a self-proclaimed "Men's Rights" lawyer, who insisted that "Ladies Night" promotions such as half-price drinks and cheaper admission were unconstitutional, a result of "40 years of lobbying and intimidation, [by] the special interest group called 'Feminism.' "
Something tells me that Hollander is a little off in his assessment of blame; it doesn't sound much like the feminism I know to "lobby" and "intimidate" in favor of men paying for women as entertainment and to get them liquored up. In fact, it sounds pretty anti-feminist to me already, but then I'm not a self-proclaimed "anti-feminist lawyer." Clearly he's an expert on the topic.
It's not a huge deal, but I'd never enter a bar that advertised a ladies night (I've never seen that out here, but then again "happy hour" started catching on in France just a few years ago), and not because it's "sexist against men," but that it's basically asking me to subsidize heterosexuality and general straight male creepiness. Plus the number of drunken women in a bar isn't something I look at when deciding where to spend my time and money.
