it's been a long time since I lived in Denver, but some interesting things to do might include going to a casino (there are some in Blackhawk), visiting the botanic gardens (if it still exists, near downtown), visiting the Coors Brewery in Golden, taking a trip to Rocky Mountain National Park, attending a concert at Red Rocks Ampitheater. There are several rustic restaurants that serve unusual food, like bison burgers, elk steaks and the like. One (used to be) on the west edge of town, called something like Little Bear Lodge. The Fawn Brook Inn (Allenspark) serves some great soup in a bowl. You might google "best five star restaurants in Denver". You might also like to visit Central City (near Blackhawk), for their antiques and mining town atmosphere.
