This is an escalator in the Rimskaya metro station. It's a bit more modern looking than some of the other stations, but that's because it opened in 1995. Many of the stations have these strange lights in them, maybe they had them left over from earlier years?
And to answer everyone's questions about Fisheria - It looked like it was a restaurant. I wasn't hungry, and I'm not really a fish person, so I didn't go inside. I'll make another trip to find out for sure, and I'll let you all know when I do!
