Finally got a chance to try Pop Up. It did live up to the hype! It's walking distance from my office and right in front of the main entrance to the Plaza. I usually am not a fan of hotels but being that this Pop Up is located toward the front and the Plaza has been renovated, I didn't notice the usual smoke smell. Service was really good. Myself and my two coworkers ordered the whole pie, that math was a better deal then their by the slice option and we had leftovers to take back. We ordered pepperoni and cheese although all the other options looked delicious too. The pizza isn't thick or thin but somewhere in the middle. It was a little greasy but I just blotted the excess with a napkin.
