I've been waiting to try this place since they announced they were building one here. Everyone in NYC raves about it. Well, it did not disappoint. They have plenty of people there, so the service is good, friendly and fast. The food was great. The burgers are rather small for the price, but the quality is top notch! The burger was great. Wasn't a fan of the shack sauce (I ordered it on the side). Call me old fashioned, but just give me a little mustard on the burger. I'm glad you have to ask for onions, if you want them... everyone should do that. LOVED the cheese fries! They are a MUST order every time. And I had a creamsicle float to drink (orange soda and vanilla frozen custard). It was quite awesome! The burger was the smaller, but it tasted the closest to Whataburger than any other place in Vegas. Loved this place. Can't wait to go back!
