I came the second day it was opened and was surprised how the hostesses and waitresses were prepared to handle their duties and not fumbling around on what to do.\n\nMy first experience was at the bar where there were plenty of beers on tap.  The Honey Brown beer was actually really good.  The bar tender was extremely nice and gave me samples of two different beers before I picked one.\n\nThen we sat down at the restaurant.  We were greeted with truffle butter popcorn courtesy of the chef and boy were they delicious.  Then I ordered the Kobe burger with fried avocado and yam with a spicy mayo sauce ($16).  This was a mighty juicy burger, but it's not as good as Burger Bar at the Mandalay Bay.  My friend ordered the duck fat fries and these were delicious with the aroma of the duck fat soaked into the fries.  My steak fries were not comparable.\n\nWe were too full to check the dessert out, but maybe next time.  Overall, a wonderful experience for a new burger joint and will return again if I visit the Cosmopolitan, although I will try out the other restaurants there before returning.  This is in between a 3-4 stars, but closer to 4 stars.
