5. The Buckhorn Exchange
1000 Osage St.
The Buckhorn Exchange – Denver’s oldest steakhouse — it holds the the state’s first liquor license—dates back to 1893. The restaurant, also a National Historic Landmark and Western Museum, serves prime grade beef as well as buffalo, elk, quail, ostrich, yak (when available), game hen, pork ribs, alligator tail and Rocky Mountain oysters (bull calf testicles), for those adventurous enough to try the “house specialty.” Delicious desserts and a unique atmosphere make it a destination dining spot.
