Operating since 1893, the Buckhorn Exchange offers an ambiance that evokes days of old, especially if your old days involved hunting and taxidermy. That said, this is one of Denver's most authentic and historic restaurants, and a dream-come-true for steak lovers. Our first suggestion: the Buckhorn's famed 24-oz. porterhouse. In the spirit of community, and a good choice for those on the paleo diet, the restaurant serves up massive steaks for sharing–from 1.5 to two pounds for two diners to 3.5 or four pounds for five, with the price for the latter currently set at $215. These beauties are carved tableside and served with a variety of goodies. Elk, quail and salmon are among other choices on the extensive menu, and ostrich and yak are available on request.
