Shake Shack originates from Madison Square Park in NYC. Anyone familiar with the chain knows they always have a line because they serve great burgers, cheese fries and shakes. I grew up with In N Out but lived in NYC for 6 years, and while I don't like comparing the two, I like both for different reasons. Yes, Shake Shack is more expensive compared to In N Out, but you get a different burger, totally different fries, and more options on shakes and malts (plus they have treats for your pup).
This location is outside the New York New York hotel and has the same look as all the other Shake Shacks. There's an express line outside for drinks only, with full orders taken inside. There's lots of seating inside and out, with TV screens all throughout the interior. Get the shack burger, cheese fries and any of their shakes. You won't be disappointed.
