Been going to NY NY for years on my Vegas trips (though I often stay at other casinos on the same trip as I am glad to take the comp rooms). First I need to say that MGM casinos (of which NY NY is one) as well as Caesars/Ballys casinos can shove their resort fees up their... (well, you figure it out). As a stock holder in both casinos, hurray! But as a "pleasure gambler", that resort fee is the biggest scam EVER. Good lord, you'd expect the MOB to still be running Vegas by coming up with "a resort fee"!
On the positive side, though this casino shares the name of one of the largest cities in the world it has the feel of a "small hometown". It's easy to get around, has a nice "flow", and has everything the major sized casinos have. It has a nice variety of slots (I'm a slot player), though in recent years I've seen far too many Asian-style slots (the kind of slots you find being sold on eBay), and far less "theme slots" (like "I Love Lucy", "Saturday Night Live", "Twilight Zone", "Star Trek", "Happy Days", etc.), which is the kind I most enjoy since they have a high "entertainment value" over just the "hey, I'm addicted to slots and gambling" factor.
Drinks could come a little faster at times, but not too bad. Machines are about average on "looseness factor". The piano bar area can be noisy as a drag race at night when the "regular crowd shuffles in". The area with restaurants (which look like a New York street) are visually appealing and the food is good (especially the pizza).
Speaking of food, almost every one of my Vegas trips starts with a stop at Nine Fine Irishmen restaurant in the casino. Excellent Shepherd's Pie and the Fish & Chips are good (as long as they drain the oil before dumping it in the basket). Can't go wrong with a Guinness to start the trip either.
Overall, nice staff (especially Players Club people)! Rooms are nice, smell clean, very comfortable. This is a excellent choice for a place to crash while in Vegas (on the flip side, Planet Hollywood rooms were humid, musty, AND stinky!)
