Not exactly a "secret" but the pizza is pretty good here! They sell pizzas here by the slice and only have about 2-3 flavors you can choose from. My bf and I got the mushroom pizza and were still pretty hungry afterwards so we went and got the meat pizza as well. The pizza is pretty thin which I like and it's pretty good. The price is at $5 per slice which is pretty pricey but that's to be expected everywhere in Vegas so that's not such a big deal. Overall, I would definitely come back here if I was craving pizza, especially late night pizza because they're open pretty late (or should I say early). Definitely worth a try if you're in Vegas and venturing to cosmopolitan, or if you're clubbing at marquee and have the drunchies after leaving the club.
