If you are considering taking a helicopter tour of the Grand Canyon, I recommend the breakfast champagne package offered by Maverick. Lovely and easy way to visit the National Park without having to drive 5 hrs or so. Was there a few weeks ago and had fantastic meals at Fleur, Scarpetta, Hot and Juicy, and Culinary Dropout. I don't think you can go wrong eating anywhere in Las Vegas
Hope your trip is fun!
