There are a large number of casinos in the former Soviet Union -- Poland, Hungary, Czechoslovakia, Ukraine, as well as Russia proper. Most are fairly run but are controlled by the Russian Mafia for the most part, Especially in Moscow & St. Petersburg. An interseting aside -- you do not have to wear suit & tie but "sports clothes" are prohibited. (Jogging suits, even silk, etc. are considered "gangster wear"). I was refused entrance because I was wearing black New Balance walking shoes. Went back the next night wearing my Hush Puppy Wing Tips, took them for $60 and some chips, and left.
