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.
