From their website:

The lounge is a tremendously lavish space in our museum in which women can indulge in decadent nibbles, fancy tipples, and other ladylike pleasures—hosted and entertained by the fabulous butler. And as is always the case with Kirsha’s dinners and feasts, you are a participant in what she sees as the art itself, part of a living installation. Any and all ladies are welcome.

Any and all ladies doesn’t sound like they are excluding people that may not have been born female. It sounds, at least to me, that it includes said person group.
