My wife and I are taking a cross-country road trip adventure to Vegas from Chicago for a week. We’re visiting places you see on “Diners, Drive-Ins, & Dives” on the Food Network when we go through Kansas, but the show never featured any restaurants in Colorado, and we’re stopping over in Denver. So what is the one thing we absolutely need to try in the area (or from Denver on the way to Vegas) or the best restaurant with food we can’t get in Chicago. Any suggestions?

Papa John’s Pizza founder and chief executive John Schnatter hit the road Wednesday on a cross-country road trip, part of a previously announced promotion celebrating his chain’s 25th anniversary that is centered around the prized possession he sold in 1984 to open his first restaurant: a 1972 Z28 Camaro.
