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!!!!!
