Haha, me too! That's in my neck of the woodsThere are some restrooms, as opposed to mere bathrooms, that have a separate adjoining room with chairs and couches for resting. It's rather like a small lounge. I have seen these, for example, at the Musical Arts Center at Indiana University in Bloomington, Indiana. There are places that have 'women's lounges' and 'men's lounges" which is another phrasing for these sorts of restrooms.
"Restroom" then became a polite way of saying "bathroom" in public. "Powder room" is another term that has been used. This usage stems from the fact that there was a room adjoining the bathroom where women could powder their faces etc. before joining everyone else. I have seen these also in a few instances on the same university campus in other buildings.
