This is not really a night club spot but obviously a popular activity. Buy your own booze and make your own fun in Whitehorse. It is obviously popular as this busker decided to set up shop on the front steps.
Now to my recommendation. There is going to be tonnes of choices. I am recommending you try out some of the local beers. If you like a light beer try the Yukon Gold or the Chilkoot. If you like an Amber beer try the Artic Red. Believe me that micro-brewing is popular in the Yukon and these beers are great!
Here's a little more on the Chilkoot Lager.
Malt - Pale
Hop - Cluster
Original Gravity (Balling): 11.6
Final Gravity: 1.9
Alcohol by volume: 5%
Primary: 7 days @ 120°C
Secondary: 3 weeks @ 1ºC

Earlier I recommended the High Country Inn as the place to stay in Whitehorse and one of the main reasons is the character of the hotel and the dining and drinking area with heated deck also called the Yukon Mining Company.
It is great place for food and local beer. Be sure to try the Grizzley Beer!
I remember really enjoying the menu as well, it is in the format of an 1800's newspaper with lots of local history and price comparisions from back during the Gold Rush Days. You can see a copy of it if you visit the High Country Inn web site and go under "Dining".

Lizard's is in my own humble opinion the best spot in Whitehorse. There is always local rock band entertainment, nice clean bar, lots of activity and overall a great place to have a great time in Whitehorse.
On a Friday or Saturday night it will be one of the best places to visit.

The restaurant Giorgio's has amazing food and great atmostphere. It is just like being in the middle of downtown Toronto or Italy itself.
The food really is great and the decor and atmosphere of the restaurant match.
I recommend a visit here. The pizza's are great, fettecine alfredo and if you like Octopus that is one the menu too!!
Dress Code: Whatever you would enjoy wearing!
The Two O Two is Whitehorse's country western bar. Everytime I have been there, there has also been local live country entertainment.
There is a mix of local people with tourist. There seems to be a good atmosphere, you just have to be a little careful like in any bar I guess.
It is helpful as well if you know how to do the two step a common country dance. I particularly am not that great at it at all, but it's fun learning!

Blue Moon is a local bar located right in the downtown area. On arrival in Whitehorse a lady at the rental booth in the airport proceeded to give some local bar advice after being asked and she strongly recommended not going into this bar or a stretch of three or four others on the same small little stretch.
So ignoring her advice we thought we would see everything there was to offer. It is now my advice to skip over the Blue Moon as well. Like ever town you have your crowd. It is a rough bar, plenty of signs on the walls insisting there will be no drugs tolerated.
You will notice on the sign as well that is is called a liqour store. This is different in that in Yukon you can by what they call off sales or liquor to take with you from the bar mostly used for buying beer.
If your like me you'll probably still have to take a peak but I wouldn't get out of control!!!

Dawson City is the best place for this from the casino(this is pictured: Diamond Tooth Gertie's) to the half a dozen bars all located in the city center, naturally in walking distance. The bars are usually very full of people, workers, and hopping with energy and often live music. Sometimes the situation can get a little roudy and there is the occasional slightly rough local, but take it in stride and enjoy.
