I've only heard people rave about this place in New York. They finally opened one up on the West Coast. Vegas of all places. Why not? Tourists galore and it fits within the hole idea of being "in New York" since it's located at the New York, New York Hotel.
If you take a taxi, you have to pretty much make your way onto the Las Vegas Strip outside.
Ordered a Single ShackBurger and Cheese Fries. My gf got the Shack Stack and regular fries.
My ShackBurger was okay. It reminded me of a Wendy's burger. My girlfriend's Shack Stack is a burger with a big piece of breaded mushroom. That was alright except for the fact that it's priced at $10. Worth $10? No way.
As for the Cheese Fries. Eh. Cheese sauce on crinkle-cut fries. Didn't wow me. The regular crinkle-cut fries, it works.
Not sure how people can compare this to In N Out. This place reminded me of Wendy's. Sorry. Not to say I wouldn't come back. It's not something I'd crave.
