What happened here? Stopped by today for a slice with high hopes - and given its pedigree, why wouldn't I? Secret Pizza at The Cosmopolitan is rightly a Vegas institution, and Those Guys Pies in the Lakes is my pick for the very best pizza in Vegas. But the pepperoni slice served here was disappointing. The crust felt flat, stiff, almost crackery, in comparison to the rich and doughy texture of the Those Guys crust. I contemplated tossing my crust away unfinished - a canary in the coal mine when it comes to pizza. Nothing special. I won't be back.
