Click to embiggen. The sign says “Cultural Oligarch Restaurant”, and the funny thing is that it’s supposed to be written in old-fashioned (pre-revolutionary) spelling, but they got it appallingly wrong. I guess if you’re a cultural oligarch you get to make up your own spelling.
EDIT: Actually, I think a better translation than “cultural” in this context would be “cultured” or “civilized” or maybe even “educated”.
