We also saw one - I think the 'realest' one - at the Amir Temur Museum, a surprisingly great museum off the main garden-y square area called Amir Temur Khioboni, so pretty and green. It's where the giant Soviet Hotel Uzbekistan stands. Pretty nice square.
The museum was definitely a high point, restoring my ability to go to museums. Also it had a toilet, which was actually hard to find out and about in the city. I think it was one of the hardest places for me because there weren't cafes or more museums I could pee in, it was all mosques that didn't have bathrooms and madrassahs that I wasn't allowed in. Darn. Luckily on one stretch of busy road from the Mosque Central Square back down to the regular center of the city, we chanced upon a sort of mall. It was DESERTED, but open and it had a bathroom. But like...it was deserted. We were the only people in there and every storefront was shuttered. Soooo weird.
