New York, New York was a great place for me to stay at in Las Vegas. Great Irish bar inside. Nice hotel. The MGM grand across the street had the biggest, best buffet I've ever seen. I didn't go in but The Coyote Ugly bar is also inside New York, New York. I hear its a great nightclub.

Lot's to do in New City, but make sure you go to Vax's favorite watering hole called Stout NYC. Fabulous place with the best fish and chips I've eaten.
