I have visited this place a few times since it has been open and for the most part I like the ambiance and food.
Dinning room service is a bit lacking for a Las Vegas Steakhouse but not horribly bad. Had a great server there that we followed from Austins but alas he has moved on to greater things.
I would definitely recommend forgoing the dinning room and just pull up a seat at the bar. You get the same great food and drinks but in a more relaxed environment. The bonus is you are served by some top notch bartenders. They pour a mean martini...
As far as food, the Prime Rib is so so, but the Filet and Ribeye are superb. The creamed corn and the spinach and cheese tomato are their best sides. And the seafood is not half bad, $50 for a lobster tail is a good deal for a steakhouse.
