My experience at the Cosmopolitan was a complete fluke. My mother and I walked in because my younger brother had stayed there for Spring break earlier in the year and we just wanted to see what it looked like.
Firstly, the lobby of the casino is absolutely gorgeous. After doing a lap we were going to head out to our next destination, but I noticed a $10 black jack table and decided to sit down and play just "a couple of hands."
What was supposed to be a "pop by" turned into a three hour gambling extravaganza. The two dealers that rotated back and forth at our table didn't mind giving hints to players (making the game very fun instead of intimidating which is sometimes can be) and the servers came by to offer libations on a regular basis. After three hours of the most fun I have had gambling EVER we decided to quit while we were ahead and ended up leaving with a nice little chunk of winnings.
I will definitely plan visit the Cosmopolitan again on my next trip.
