The location on Ontario street is closed, which means the location on St Laurent in Little Italy has the owners' full loving attention. The story as I heard it is that they turned down spots at top salons in NY and Paris to open their own place where they could hire and train easy-going people, sell ultimate frisbees, and be near family and friends. For around 50$ you can get the best looking 'do in the city in a totally chill, fun environment. These are haircuts that go seamlessly from family dinners to professional environments to rock shows. I have been here when full bridal parties are getting their updo's done and everyone looks chic, romantic, unique, but unified - it really is amazing. (Also amazing was getting my hair cut downstairs where there are only 2 salon chairs and NO bridal parties. Thank you for the blessed quiet!)
I asked around a lot before coming here after my last guy moved away, and all the gals with the best hair pointed me to Queen of the World.
I should add - I always get my hair cut by the owner and have never had my hair coloured here. Not a pretentious spot, always a great haircut.
