Details: There a number of carts here that are Halal Guys and a number that are imitators. The one cart that is undoubtedly a genuine Halal Guys cart is on the southwest corner of 6th Avenue and 53rd Street, New York, NY. The official site is http://thehalalguys.com/
A number of years ago I came here once under the pretense that this was the best halal cart in New York City. To my recollection, I paid around five dollars for what was arguably the best halal in the city, though not by a wide margin. Fast forward to the present day, and while I can say the food is about the same as it was the last time I had it, the price isn’t.
