We came here for dinner on our recent trip to Las Vegas, and after much anticipation decided it was totally not worth it.\n\nThe staff was friendly but very clearly overwhelmed.  Our waitress had just been triple-sat with 3 new tables at once and took quite a while to even get to our table for our initial drink order.  We like to get a good sampling of menu items on a trip to a new restaurant, so we ordered a few items from each section.\n\nThe appetizers were probably the best part of the meal, and that's not saying much.  The arancini was served with a tasty aioli, without which the dish would have been forgettable.  The pizza we ordered was overly salty, burned in places and raw in others.  (If you want good pizza in the Cosmopolitan, ask any of the staff about Secret Pizza! Down an unmarked and unassuming hallway between two other restaurants is a gem of a New York style pizzeria.)  My grilled octopus was tough and rubbery, clearly overcooked.  The worst and most unforgivable part of the meal was one of our pasta dishes, the oxtail raviolini.  I bit into one of these flavorless pouches only to bite down on a LARGE PIECE OF BONE!!!!!  This dangerous and costly flaw killed the meal, so we paid our bill and left.  And no, we did not take the leftovers with us.\n\nIf you want much better Italian food for a not too much higher price, I suggest Scott Conant's other restaurant in the Cosmopolitan, Scarpetta.  Good food, portions, and service combine with reasonable price (when compared to other fine dining restaurants in the area).\n\nOn second thought, I'm downgrading this restaurant from 2 stars to 1.  There really are much better places to spend your money, and that bone fragment was unacceptable.
