I come here to ride the rollercoaster and play the arcade games when I am in Las Vegas. They do a good job of capturing the New York atmosphere, right down to hiring a lot of people who are apparently from New York or very good at faking the accent. The coaster itself is a lot of fun, especially if you like vintage-feeling bumpy coasters (it feels like a wooden coaster) as opposed to super smooth rides.
Getting on the coaster is not as much fun as actually riding it because you have to rent a locker for all your stuff. You can't just leave your glasses or cell phone or whatever on a shelf when you get on and grab it when you get off - You need to rent the locker. Since you have to walk quite a long distance to get to the coaster after you put your stuff in the locker, it's a bit of a hassle especially if you left your glasses and can't see without them. Also if you want to ride twice they make you go out and come in again even when there is no line. Finally, when you leave you have to go out through a very overcrowded souvenir shop.
I like the arcade game room and again it does a pretty good job of capturing a New York amusement park vibe. It tends to be way full of kids though since they have to have something to do other than the casino and this is one of the only options available.
You have to walk what seems to be a super long distance through the casino to get to any of this fun stuff, which is a pain. The casino itself seems overcrowded and a bit grubby and noisy, which puts me off from actually renting a room at this establishment.
