Carnevino is a good steakhouse.
The one thing I did notice that the waiters did a good job at was the art of "upselling" which wasn't necessarily coercion or strong armed but a somewhat continual, not necessarily aggressive, but reminders of the fixe menue higher priced items and the "per person" (so, to some if you see $80 for a steak but don't read the "per person" you might actually be better off with the $60 steak on your own than sharing one for $160). So, the service was friendly, and attentive, but I just thought, knowing the restaurant business, the staff are trained to route patrons to raise the AOV (average order value) per customer, and the efforts seemed apparent, 'tho not in an offensive way, more in an obvious subtle way of them just doing their job.
For that reason, I'd say the food is excellent and deserves * * * * for sure, it's right up there with CUT, Delmonico's, Prime, SW, and the rest of the high end steakhouses in Las Vegas.
But, I think in terms of the pricing and value, I'd take the rating down a notch. If Yelp allowed 1/2 stars, I'd make this a 3.5 - - and granted my rating system is where:
"* * *" (three star) is GOOD, solid and nice, even recommend or come back to
"* * * *" (four star) is GREAT, that I'd highly recommend to others
"* * * * *" (five star) is a knock your socks off totally AWESOME,
* *" (two star) is merely Okay, but still not bad and I'd go back to again.
"*" (one star) is given where something outright offended me, usually based on service and a lack of effort.
So, Carnevino is good, bordering on great.
The venue is nice at the Palazzo. I generally love the area of The Venetian, Palazzo, Encore and Wynn. The restaurant itself has a good vibe to it, not too loud or crowded feeling.
I had the Porterhouse to share. The fillet portion was pretty small, and the New York side was good. I sort of felt or speculated for the $160 for 2, I could have actually eaten the entire steak myself for 1, and we may have been better off ordering separately the NY and the Filet Mignon for either a lower cost or a bigger portion (maybe not dry aged to the bone as the marketing hype machine says, but I'm sure tasty nonetheless).
