Ehh more like 3.5 stars but closer to the three side than four side.
I come here when I'm looking for a quick and affordable meal in Vegas, sober or drunk. It's open into the wee hours of the night which makes it a great spot to come to after a fun night of Vegas shenanigans. Expect a long wait if you're going to Vegas on a big holiday weekend or during the summer though (I've had to wait close to 40 minutes in agonizing pain before...thanks, heels).
They offer a variety of pizzas, and I always go with some sort of meat combo. It's served NY style and is a perfect thin crust. Slices come out to be around $5 or more depending on the toppings your pizza has. Affordable for Vegas, but $5 for a slice of pizza is pretty ridiculous elsewhere. Their slices are also pretty greasy which is a downside and definitely doesn't sit too well especially when you're drunk off your butt; delicious for the time being but regretful afterwards.
All in all, it's a good spot to come to when you're in Vegas and want a decent slice of pizza. The fact that it's "secret" and is located through a corridor also makes it a pretty cool spot.
