STK at Mirage is yummy, anything at the Wynn. Pannevino near the airport is my favorite for fine dining.For lunch Slice of Vegas in Mandalay is nice and Veggie House in China Town is wonderful. Ronalds donuts is a great choice for the am.

Okay nacho daddy isn't fancy but it's just too good for me not to mention. I had the lobster tacos there. As far as nicer goes top of the world is a great choice!

Sinful

I like the allegro at the win, it's open super late night too , as late as 5 am and it offers such better options then anything that has the word cafe attached to it. Ask for their fillet mignon, its off the menu but is always avab.

I just googled that and here are your top 10! https://www.tripadvisor.com/Restaurants-g45963-Las_Vegas_Nevada.html

Enjoy!

Not in any particular order.

1.  Lago at Bellagio.  Great mederitranean food and the drinks are good.  Get a table on the patio or close to the window and you'll have a great view of the Bellagio water fountain show.  Not terribly expensive.

2.  Mon Ami Gabi at Paris.  Absolutely fantastic for all three meals of the day.  My favorite is having breakfast on the patio and watching the world walk by.  Great menu, great food and great service.  It won't break the bank.  

3.  If you like burgers give Shake Shack at NYNY a go.  Not expensive and quality burgers fries and shakes that are de-lish!!!

4.  Peppermill (between SLS and Wynn). If you want to get your eat on this long standing restaurant will see to it that you leave with a full stomache or a doggie bag or two.  Also, check out the Peppermill Lounge, behind the restaurant, for at least a drink.  It's been a mainstay in Vegas since the 70s and is pretty much a must do on my twice annual trips.

5. Lots of great steak houses at almost every property. My fave is Prime at Bellagio.  This too, has a great view of the Bellagio fountains.  

There are a lot of very good restaurants downtown and off strip.  If you might be interested in any of these shoot me a pm and I'd be glad to help in any way I can.

Hope you have a super trip!!!!!

Sit outside, and order anything on the menu.  You'll pay about half of what the "celebrity chefs" get and  your meal will be  great!  Servers are great too...

If you are REALLY SERIOUS about burgers you must check out Hubert Keller's Burger Bar in the  Mandalay Bay mall. The Keller Burger is to due for! Add a chocolate malt and you will be un heaven! Thank God the music is loud in there because you just may orgasm from the experience, it is THAT good!

Mastro's Ocean Club- the steaks, the appetizers, the wine selection, the butter cake...truly a treat and you can't go wrong.
Recently went to Scarpetta at the Cosmopolitan and really enjoyed it.
