I'm not a huge fan of the West Texas plains, but I've always been surprised at how much I like Amarillo. It's a very funky, livable city. Many artists live in Amarillo due to the lower than average cost of living, and the Historic 66 District downtown is the center of Amarillo's art community. Public-art displays such as the Cadillac Ranch along Interstate 40 and the Dynamite Museum, a series of mock road signs located throughout the city, add to Amarillo's eclectic appeal.
One of the most famous attractions in Amarillo is the Big Texan Steak Ranch. At the Big Texan, if you eat a 72-ounce steak in less than an hour, you get your dinner for free. It reminds me of that restaurant in "The Great Outdoors" with John Candy. While I've never been tempted to try it, I will report that the Big Texan, although touristy, is a lot of fun, and the normal-sized steaks are very tasty. Amarillo is also home to the largest number of Laotian restaurants in Texas. These are definitely worth visiting, especially if you like spicy food.
