What is not clear in the OP's post is his/her degree of passing and without knowing that, there's no good answer to the question. I think if you are clearly a "dude in a dress" with bald head and a beard, you had better stick to the men's restroom. If you are trying your best to pass as a woman, the woman's room would be a better choice if there is no alternative.
