It was a pain in the ass to find the first time around, but who can forget a place like this after trying Secret PIzza's delicious NY style pizza.
We got a white pizza and a pep and sausage pizza when we first came here and with every trip since then, this is the first thing we pick up after finding our hotel room.
I would suggest ordering a whole pizza and eating on the spot if you aren't staying at Cosmo. You'll be able to enjoy each bite the way it was intended right out of the even. Just hope that there is a spot to sit down and eat as it does get pretty packed depending on what time you go. Unfortunately, it was packed one time and we took a taxi ride back to our hotel after picking up the pizza one time. By the time we got back it wasn't as fresh, hot, and tasty.
The down side is that the pizza is REALLY greasy so if you're a health nut you might want to stay away. If you are going to order a whole pizza, it does take a while for it to come out. Also, if you order by the slice, beware its not going to be as good as when its right out of the oven. My girlfriend and I bought two slices that were sitting out and man were we disappointed. They even reheated it for us in the oven. The price is also pretty high...$20 for a whole pizza if I remember correctly.
In the end, the positives outweigh the negatives. Imagining the tastes of each bite at this moment gets my mouth watering. Secret Pizza is a place I would recommend to anyone who loves pizza and is in Vegas. And if you don't, maybe this establishment will change your mind. It's that good!
