Las Vegas is amazing if you're over 21. Kind of boring if you're not though, because you basically have to be 21 or older to do anything there. I would recommend New Orleans because even after Katrina, it's still had an awesome night life, great music, great food, and a lot of unique sights to see. One of the coolest cities I've ever been to. However, the oil spill in the gulf coast region has put kind of a damper on the fishing industry there so I'm not so sure about great food at the moment. I'll have to ask my aunt, she chaired the New Orleans tourism board for some number of years and still does work for them.
