This is a place for real Bush Pilots and explorers (mostly geologists looking for minerals in the Canadian tundra). So there are no real tourist traps!!! Perhaps the closest thing Yellowknife has to a famous/touristy spot would be the Wild Cat Cafe...but even that's pretty cool for a local joint.
Wildcat Cafe. Nice place, food is OK but not great, but has been increasing in price every summer. No longer worth it in my opinion.
