If I could rate more than 5 stars, Napoleon's Piano Bar would definitely get more stars. The establishment as a whole is very nice and has a wide selection of alcohol as well as a great assortment of cigars. The servers were phenomenal. Very friendly and knowledgeable about pairing for cigars/drinks. This place is definitely not cheap so make sure to come with plenty of money, not only for drinks and cigars, but to make any requests to the dueling pianists.
As far as the performers go, they were superb! They did a great job getting the crowd to sing along. They also did a great job covering everything from Johnny Cash to Elton John.
I strongly recommend you stop inside this place if you're looking for entertainment outside of the normal Las Vegas experience. TWO THUMBS WAY UP for Napoleon's Piano Bar in the Paris Hotel and Casino.
