There are no changing tables in the men’s room. Well, there are, but they’re rare, and the ones which are there are disgusting. You wouldn’t want to put your kid on that thing.
I have found them to be quite clean (though yes, rare). The cleanest place in the Stanford Shopping Center is the men's room at the American Girls store. Or rather, it was until the store closed last year. But that men's room was very rarely used, and the changing table was pristine.
