Snooty
The most applicable term to be applied to Monte Carlo is "snooty". This is all based on when I was there in the late 80's but... everything was expensive in the whole area and in my visit to France in general. You had to wear a suit and tie just to get into the place! They are or were rumored at that time to stack the shoe, that is take out some of the 10's to hedge themselves in.
I was in Toulon and Marseille and heard that they had buses that you could zip over to this place, so I went. Vegas it AIN'T, BABY! Stuffy, snooty, arrogant bunch of weinies that stack the shoe and are all about fleecing tourists? I wonder if it is still the same after all these years.
