Monaco is a tourist trap with only two attractions - Grace Kelly and Grand Prix. And one is dead. I recall a USENET post explaining years ago one of their casinos refused to redeem some chips. I didn't feel like dressing up and paying admission (to the old casino) to play a crummy game in a paranoid place.
Monte Carlo is a tax haven, so there are many luxury cars. But I am suspicious about the luxury cars parked conspicuously in front of the old casino. I'll bet they are the same cars everyday. And inside they probably have a shill pretending to gamble a lot of money to impress gullible tourists. Then the tourists can gawk at pictures of Grace Kelly and the Grimaldi family. Where did Prince Rainier get all his medals anyway - presumably he awarded them to himself?! Outside they sell tacky souveniers.
Go to the perfume factory or medieval city instead. Or go to the beach or try French dining. There are many small French casinos. The rules are standardized with two different colors of cards. Please report back specifics of rules, penetration, and shuffle.
