The bathrooms at San Francisco's Slanted Door restaurant are interesting. They're like a hybrid setup - a hallway in the middle, with 5 or so toilets behind doors to the left, and sinks behind no doors to the right.
The toilet rooms are clean and accommodating, if unremarkable. Same can be said about the tray of sinks.
But the setup has an inherent problem - nobody wants a row of sinks meant to be shared for men and women. It's weird. I don't want to see the beastly women of San Francisco attempt to cover face with makeup, and i'm sure they don't want to see me checking for boogers (or maybe they do).
I would have much preferred the traditional setup of separate room for men and separate room for women. Or, at the very least, separate unisex rooms in the style of Maialino.
