I'm not saying you should read at lunch. I am not saying you should have a liquid lunch. All I'm saying is that if you are looking for a way to spend a little time enjoying a meal and gaining a little knowledge I have the spot for you. Head to Public House at Palazzo Las Vegas and chat up the Cicerone. While you are there you should probably have one or two or five of their beers since the list is so extensive it would be rude not to. The food should impress you since there is quite a few fabulous items on the menu. ( Avoid the burger, it's a bit of a mess and at $19 a little ugly on the wallet, see my Best Burgers in Las Vegas for better choices)
If beer and modern tavern food are not what you are looking for head to The Top of The World Restaurant at the Stratosphere Tower for a view and some dynamic flavors. Need a margarita? Try the comfort food at Cabo Wabo with a seat right on the Las Vegas strip. You can go romantic at Olives at the Bellagio or satisfy the your sweet tooth at Serendipity 3 at Caesars Palace.
There are so many food options for lunch in Las Vegas that I could go on forever. Here are a few more suggestions for lunch in Las Vegas and if you still are not sure about where to eat send me an email or find me on Twitter and I'll be sure to let you know where I'm currently eating.
