There are different strata of the Vegas experience. Everything from clubs, to gambling spaces, to restaurants, to special interest activities, etc. The Vegas one experiences while moving along like cattle on the strip is merely one layer of a very big onion (for lack of a better word).
There are spaces hidden in plain site or open to only those who know of them and the process to access them. Some bars contain speakeasies that you gain access to by ordering a drink with a particular change to the standard recipe, etc.
"Old fashioned, two cherries, thank you." If you use that exact phrase, by the time your drink is done in 20 minutes a woman appears and says your table is ready and quietly takes you away while other bar patrons are none the wiser. Through the kitchen you go, down a stairwell, along a dark hallway, where you suddenly enter one of the most beautiful bars you could ever imaging where every drink is coupled with a cigar and only the finest liquors are served.
Vegas has mastered the art of parting you with your money and that's before you ever set foot in a "casino."
