> First, legal problems: you can't have a unisex multi-stall bathroom in the USA. I'm not sure if it's actually illegal (it probably is in many states), but it'll never fly even if it is.
Granted it's not the same as an office bathroom, but I know of at least one mid-price but trendyish restaurant with a unisex multi stall bathroom here. And I'm in surprised-we-don't-have-a-trans-bathroom-bill-yet Missouri.
Are these stalls typical stalls with a huge gap at the floor so you can see the neighbors as they sit on the pot? Are they actual separate rooms?
I've been in a few nice restaurants where the "stalls" were actually separate walled, tiled rooms with nice wooden doors with locks. Those bathrooms are a real joy to use compared to standard public restrooms. The darker tiles and wood and dimmer lighting and nice fixtures are also really nice. While the ones I was in were not unisex, I could see how that would work just fine, since the only area shared is the area with the sinks.
