While not actually on Route 66, Las Vegas is so close we figured why not! From Flagstaff, we drove to Kingman, AZ for lunch at Mr. D'z, a famous Route 66 diner. Decked out in turquoise and fuschia, this 1950's-themed eatery is best known for its burgers and homemade root beer. It has served notable celebrities over the years, including Oprah Winfrey (again, on her cross-country adventure with her best friend, Gayle King), who apparently ordered a burger, onion rings and a root beer. I enjoyed my sandwich and onion rings but it was the pistachio milkshake that left me craving more. Mind blowing, seriously! From there, we drove north to the Hoover Dam, where it was a sweltering 45 degrees celsius, and onward to Las Vegas, where we spent days six and seven of our Thelma and Louise adventure. Our Vegas stay included cocktails at the Mandarin Bar (Mandarin Oriental Hotel), Vista Cocktail Lounge (Caesars Palace) and The Chandalier (Cosmopolitan Hotel), dinners at Sage at Aria and Giada (at the Cromwell Hotel; the most delicious meal I've had in ages), brunch at Mon Ami Gabi, pool time at Drai's Beach Club and, of course, walking the strip.
