If you've never had Halal Guys in New York City, then this place is just alright, mediocre at best. If you've had it in NYC, don't even try it. I'm not trying to be mean or harsh. It's the simple truth. Before it opened here, I craved street halal ALWAYS. Now that I've had Vegas' version (and yes I am local), I don't crave it ever because I rather just not have it until I can get it right from the big apple.
I want to say it has to do with the preparation. When you order from the street carts, they throw it on their grill and you get your food nice and hot. Here, the meat is in warmers as if you're at Chiptole. It's simply not the same. The flavor is not the same. And if you're expecting your food to be drenched in the sauce as it is in NYC, it won't be.
Don't get me wrong though-- it's still better than other fast food places. It's just not up to par with the expectations the original street halal carts caused me to have. So I don't know if it's their fault or this branch's fault, but I wish it could be better. Super anticlimactic when I was so excited to finally go try it after it opened in Vegas. Darn.
