The Bordello Dining Rooms were located at the Hotel Bonanza.

I'm showing two menus here. The first is one is small...a single piece of cardstock, a little larger than a postcard. The second one is slighty larger... maybe about 7"x10", or so. The creases in that one make me think that a man rescued that one, folded to fit the inside pocket in his suit jacket

When I googled, I found a facebook post from someone who said he started as a busboy in the Bordello Dining rooms when they opened in 1967. He also mentioned that they were private dining rooms, upstairs, in the Bonanza.
